Replace `oclif` with `cli` (#744)
Summary:
This commit changes the CLI to use the code in `cli` instead of `oclif`.
A subsequent commit will remove the dependency on OClif altogether.
Resolves #580.

Test Plan:
Note that `yarn backend; node bin/sourcecred.js help` works. Note that
the documentation in the README is still correct.

cli: add `main`, `sourcecred`, and `help` (#741)
Summary:
This commit includes a minimal usage of an actual CLI application. It
provides the `help` command and no actual functionality.

Test Plan:
Unit tests added, with full coverage. To see it in action, first run
`yarn backend`, then run `node bin/cli.js help`.

cli: rename existing system from `cli` to `oclif` (#739)
Summary:
Per #580, we aim to remove OClif. To do so, we move the old system to a
directory `oclif`, and will create the new system in the now-vacant
`cli` directory.

Test Plan:
Note that `yarn backend` still builds, that `node bin/sourcecred.js`
still has `help` and `load`, and that `git grep -wc cli` yields only
`yarn.lock:9`.

Allow backend `process.env` to see the runtime env (#748)
Summary:
This is a follow-up to #746, wherein we exposed our fixed `env` to the
backend applications. We now extend that environment so that it can also
access the user’s runtime environment—i.e., the native values of
`process.env`.

(This is in contrast to the frontend bundles `main.js` and especially
`ssr.js`, where this is not and should not be the case: the environment
must be fixed at build time.)

Test Plan:
Add to the top of `async run()` in `src/cli/commands/load.js`:

```js
    console.log(require("../../app/version").VERSION_SHORT);
    console.log(process.env.AT_RUNTIME);
```

Run `yarn backend` and `AT_RUNTIME=wat node bin/sourcecred.js load`.
Ensure that the version number and the string `wat` are both printed.
(Before this patch, the string `undefined` would be printed instead of
`wat`.)

Expose `env` to backend applications (#746)
Test Plan:
Add `console.log(require("../../app/version").VERSION_SHORT);` to the
top of `async run()` in `src/cli/commands/load.js`. Run `yarn backend`
and `node bin/sourcecred.js load`, and note that it prints the current
version number. Before this change, it would have raised an error:

```
Error: gitState: not a string: undefined
    at parseGitState (~/git/sourcecred/bin/commands/load.js:1160:64)
```

because the requisite environment variables were not included.

Also, `yarn test --full` passes.

Add a configurable feedback URL to prototype (#715)
Summary:
We can now set, at build time, a URL to be displayed at the top of the
prototype, encouraging users to provide feedback. If the URL is not
provided, it defaults to the appropriate topic on the SourceCred
Discourse instance.

The result looks like this:

![Screenshot of the feedback URL in the prototype][screenshot]

Test Plan:
Unit tests added to `yarn sharness-full` and `yarn unit`.

You can run `yarn start` to see the message with the default URL, or
`SOURCECRED_FEEDBACK_URL=http://example.com/ yarn start` to specify a
custom URL.

Add `GitState`, `Environment` to the `VersionInfo` (#692)
Summary:
The version number displayed in the application now displays much more
specific information. It now lists the Git commit from which the build
was constructed, and will identify whether we have accidentally deployed
a development instance (which would be slow) or an instance with
uncommitted changes (which would be bad).

The version information is computed during the initialization of the
Webpack config. For development, this means that it is computed when you
run `yarn start`, and not updated thenafter. If the stale information
presents actual confusion, we would need to backport Webpack 4’s support
for runtime values in `DefinePlugin` to Webpack 3 (or upgrade Webpack
by a major version).

Test Plan:
The logic for `GitState` and `Environment` has existing tests. With both
a clean tree and a dirty tree, run `yarn start` and build the static
site, and check that the resulting versions are correct.

Don’t pass through REACT_APP_* env vars (#688)
Summary:
We don’t use or want these. Injecting an arbitrary family of variables
from the client’s host environment seems like a Bad Idea.

Simplify `getClientEnvironment` (#687)
Summary:
Cargo-culting `reduce` doesn’t make something “functional” or “good”;
forcing a `for`-loop into a `reduce` with impure callback is abhorrent.

Test Plan:
Into `config/stopship.js`, write:

```js
console.log(JSON.stringify(require("./env")()));
```

Then run `NODE_ENV=test node config/stopship.js` before and after this
commit and note that the output is identical.

Remove remaining public URL logic (#686)
Summary:
Now that the main functionality of #643 has been implemented, we no
longer have any use for the “public URL” property. In fact, its presence
is actively harmful, as it suggests that the gateway may be known before
runtime, which is confusing and false.

Closes #643.

Test Plan:
Running `yarn start` works. Building the static site works.
Invoking `git grep -i 'public.\?url'` finds no matches.
Also, `yarn test --full` passes.

Use relative paths for lexically static assets (#671)
Summary:
This is the first observable step toward #643. Assets whose paths are
known as literals at server-side rendering time are now referenced via
relative paths. This means that the favicon and JavaScript bundle can be
loaded from an arbitrary gateway. The actual bundle code will still only
work when loaded from `/`.

This commit stands alone so that the enclosing change to the Webpack
config can be in as small a change as possible.

Test Plan:
  - Note that `yarn start` still works.
  - Run `./scripts/build_static_site.sh` to build the site into, say,
    `/tmp/gateway`.
  - Run a static web server from `/tmp/gateway/` and note that (a) the
    paths listed in the page source are relative, and (b) everything
    works as intended, with no console messages in either Chrome or
    Firefox.
  - Run a static web server from `/tmp/` and navigate to `/gateway/` in
    the browser. Note that the favicon and JavaScript are correctly
    noted, but that the router raises an error because it is trying to
    load a non-existent route. (This behavior is unchanged.)

Add a favicon (#637)
Summary:
In addition to the obvious benefit of having a favicon, this gets rid of
a 404 Not Found error on our home page, tremendously boosting our hacker
cred.

Test Plan:
The favicon is displayed in both `yarn start` and the static site (as a
result of the build script). The added build test fails before this
change.

Remove service workers entirely (#635)
Summary:
This is a follow-up to #514, wherein we disabled new service workers and
instructed any existing service workers to self-destruct. (See that PR
for the rationale.) This commit removes them from our codebase entirely,
enabling us to slim down our build process and our build output.

Test Plan:
Running `yarn start` still works. Building the static site and exploring
it works, too.

Forbid accessing the `cache/` directory at runtime (#614)
Summary:
We plan to allow plugins to store permanent data in `$SC/data/` and
temporary, ephemeral, or intermediate data in `$SC/cache/`. The latter
subtree will be excluded from the static site at build time, so it
behooves us to also exclude it from the development environment.

Test Plan:
Run `yarn start`. Then,

```shell
$ root='localhost:8080/api/v1/data'
$ curl -sI "${root}/repositoryRegistry.json" | head -1
HTTP/1.1 200 OK
$ curl -sI "${root}/data/sourcecred/example-git/github/view.json" | head -1
HTTP/1.1 200 OK
$ curl -sI "${root}/cache" | head -1
HTTP/1.1 400 Bad Request
$ curl -sI "${root}/cache/" | head -1
HTTP/1.1 400 Bad Request
$ curl -sI "${root}/cache/foo" | head -1
HTTP/1.1 400 Bad Request
$ curl -sI "${root}/cache/foo/bar/baz" | head -1
HTTP/1.1 400 Bad Request
```

Also, check that the app still works.

Remove the `start` CLI command and dependencies (#613)
Summary:
We never use the `node ./bin/sourcecred.js start` command. This command
contains an Express server to combine the static files with the build
output, which duplicates the logic in our Webpack config, which we
actually use (with `yarn start`). Once we actually want the command line
entry point to be a useful tool for end users, we can consider
reimplementing it the right way, whatever that may be. Until then, it’s
simply one more thing to keep in sync.

Test Plan:
Running `yarn test --full` passes; the `load` CLI command still works;
running `yarn start` still works.

Add `sharness` for shell-based testing (#597)
Summary:
We will shortly want to perform testing of shell scripts; it makes the
most sense to do so via the shell. We could roll our own testing
framework, but it makes more sense to use an existing one. By choosing
Sharness, we’re in good company: `go-ipfs` and `go-multihash` use it as
well, and it’s derived from Git’s testing library. I like it a lot.

For now, we need a dummy test file; our test runner will fail if there
are no tests to run. As soon as we have a real test, we can remove this.

This commit was generated by following the “per-project installation”
instructions at https://github.com/chriscool/sharness, and by
additionally including that repository’s `COPYING` file as
`SHARNESS_LICENSE`, with a header prepended. I considered instead adding
Sharness as a submodule, which is supported and has clear advantages
(e.g., you can update the thing), but opted to avoid the complexity of
submodules for now.

Test Plan:
Create the following tests in the `sharness` directory:

```shell
$ cat sharness/good.t
#!/bin/sh
test_description='demo of passing tests'
. ./sharness.sh
test_expect_success "look at me go" true
test_expect_success EXPENSIVE "this may take a while" 'sleep 2'
test_done
# vim: ft=sh
$ cat sharness/bad.t
#!/bin/sh
test_description='demo of failing tests'
. ./sharness.sh
test_expect_success "I don't feel so good" false
test_done
# vim: ft=sh
```

Note that `yarn sharness` and `yarn test` fail appropriately. Note that
`yarn sharness-full` fails appropriately after taking two extra seconds,
and `yarn test --full` runs the latter. Each failure message should
print the name of the failing test case, not just the suite name, and
should indicate that the passing tests passed.

Then, remove `sharness/bad.t`, and note that the above commands all
pass, with the `--full` variants still taking longer.

Finally, remove `sharness/good.t`, and note that the above commands all
pass (and all pass quickly).

Remove `src/app/public` (#582)
Summary:
This subtree has no effect on the new build process; it contains only
stale code.

Test Plan:
Running `yarn test --full` passes. Running `yarn build` and running an
HTTP server on the result indicates the expected behavior, as does
running `yarn start`. A quick `git grep public` finds no amok results.

Refine the build directory cleaning logic (#577)
Summary:
We were asking the `clean-webpack-plugin` to remove the `build/`
directory in all cases. However, Webpack accepts a command-line
parameter `--output-path`. When such a parameter is passed, we would be
removing the wrong directory.

The proper behavior is to remove “whatever the actual output path is”.
Webpack exposes this information, but it appears that the
`clean-webpack-plugin` does not take advantage of it. Therefore, this
commit includes a small Webpack plugin to do the right thing.

Test Plan:
Test that the behavior is correct when no output directory is specified:
```
mkdir -p build && touch build/wat && yarn build && ! [ -e build/wat ]
```

Test that the behavior is correct with an explicit `--output-path`:
```
outdir="$(mktemp -d)" && touch "${outdir}/wat" && \
    yarn build --output-path "${outdir}" && \
    ! [ -e "${outdir}/wat" ]
```

Test that the plugin refuses to remove the root directory:

```
! yarn build --output-path . && \
    sed -i '/path: /d' config/makeWebpackConfig.js && ! yarn build
```

(Feel free to comment out the actual `rimraf.sync` line in the plugin
when testing this.)

package.json: reorganize test commands (#571)
Summary:
Running `yarn test` (equiv. `npm test` or `npm run test`) now runs all
checks. It takes the place of the former `yarn travis`. This is more in
line with the expectation of a top-level `test` command: if it passes,
your code is good.

The `unit` command now runs Jest once, not in watch mode. It takes the
place of the former `ci-test`. To run tests in watch mode, run any of
the following:

  - `yarn unit --watch`, or
  - `npm run unit -- --watch`, or
  - `npm unit -- --watch`.

This behavior is more consistent with the standard behavior of commands
like `make test`. It is also empirically what @wchargin and
@decentralion want most of the time.

Test Plan:
Verify that each of the scripts `test`, `unit`, and `coverage` passes.
Verify that each of the aforementioned `--watch` invocations works.
Verify that `.travis.yml` has the correct `script:` command.

new-webpack: clean `build/` before prod (#568)
Summary:
In our current system, we build by invoking `scripts/build.js`, which
begins by removing the `build/` directory. This behavior is nice,
because it prevents cross-contamination between builds. In this commit,
we add a plugin to achieve the same result from directly within Webpack.

Test Plan:
Run

```
mkdir -p ./build
touch ./build/wat
NODE_ENV=production node ./node_modules/.bin/webpack \
    --config config/makeWebpackConfig.js
```

and ensure that `./build/wat` does not exist after the build completes.

Summary:
This will enable us to differentiate the production and development

Best reviewed with `git show -w`.

Test Plan:
The diff with `git show -w` and the fact that `yarn flow` passes should
be sufficient. If you really want to be thorough, run Webpack with this

new-webpack: add Flow typing (#563)
Summary:
There really should be an `// $ExpectFlowError` on the dynamic `require`
on line 182:

```js
      paths: require(paths.appRouteData).routeData.map(({path}) => path),
```

However, for some reason Flow does not catch this error now, so adding a
suppression comment generates an “unused suppression” warning. We
therefore omit the suppression in this commit; we will add it later,
once Flow magically finds the error.

Test Plan:
`yarn flow` reports no errors; a deliberately introduced error is
properly caught.

William Chargin b41009b1f7 Implement a first-pass static site generation
Summary:
Some of the code here is adapted from my site (source available on
GitHub at wchargin/wchargin.github.io). It has been improved when
possible and made worse when necessary to fit into our existing build
system with minimal churn.

As of this commit, there remain the following outstanding tasks:
  - Use a non-hardcoded list of paths in static site generation router.
    This is not trivial. We have the paths nicely available in
    `routes.js`, but this module is written in ES6, and transitively
    depends on many files written in ES6 (i.e., the whole app). Yet
    naïvely it would be required from a Webpack config file, which is
    interpreted as vanilla JavaScript.
  - Add `csso-loader` to minify our CSS. This is easy.
  - Add unit tests for `dedent`. (As is, it comes from my site
    verbatim. I wrote it. dmnd’s `dedent` package on npm is insufficient
    because it dedents arguments as well as the format string, which is
    incorrect at least for our purposes.)
  - Link in canonical static data for the site.
  - Rip out the whole build system and replace it with my build config,
    which is orders of magnitude saner and less bad. (By “the whole
    build system” I mostly mean `webpack.config.{dev,prod}.js`.)

Add load CLI command (#470)
The `load` command replaces `plugin-load`. By default, it loads data for
all plugins, and does so in parallel using execDependencyGraph. If
passed the optional `--plugin` flag, then it will load data just for
that plugin.

As an implementation detail, when loading all plugins, load calls itself
with the plugin flag set.

Usage:
`node bin/sourcecred.js load repoOwner repoName`

Test plan:
Tested by hand; I blew away my SourceCred directory and then loaded the
example-github repository.

Create a bridge for the V1 and V3 apps (#448)
Summary:
Our build system doesn’t make it easy to have two separate React
applications, which we would like to have for the V1 and V3 branches.
Instead, we’ll implement a bridge to maintain compatibility.

The plan looks like this:

 1. Change the app from pointing to V1 to pointing to a bridge
 2. Move the router into the bridge and move the V1 app from the `/`
    route to the `/v1` route (e.g., `/v1/explorer`)
 3. Add a V3 app under the `/v3` route
 4. ???
 5. Delete the V1 app and remove it from the bridge
 6. Delete the bridge and move the V3 app from the `/v3` route to `/`

This commit implements Step 1.

Test Plan:
To verify that the bridge is in fact showing, apply

```diff
diff --git a/src/bridge/app/index.js b/src/bridge/app/index.js
index 379e289..72e784c 100644

and say “hello” back to the app.

Save the GitHub relational store from the CLI (#447)
Summary:
This provides a command-line entry point `load-plugin-v3` (which will
become `load-plugin` eventually), which fetches the GitHub data via
GraphQL and saves the resulting `RelationalStore` to disk.

A change to the Babel config is needed to prevent runtime errors of the
form `_callee7` is not defined, where `_callee7` is a gensym that is
appears exactly once in the source (in use position, not definition
position). I’m not sure exactly what is causing the error or why this
config change fixes it. But while this patch may be fragile, I don’t
think that it’s likely to subtly break anything, so I’m okay with
pushing it for now and dealing with any resulting breakage as it arises.

Paired with @decentralion.

Test Plan:
Run `yarn backend`, then run something like:

```
node bin/sourcecredV3.js load-plugin-v3 \
    sourcecred example-github --plugin github
```

Inspect results in `SOURCECRED_DIR/data/OWNER/NAME/github/view.json`,
where `SOURCECRED_DIR` is `/tmp/sourcecred` by default, and `OWNER` and
`NAME` are the repository owner and name.

This example repository takes about 1.1 seconds to run. The SourceCred
repository takes about 45 seconds.

Create a V3 command-line entry point (#446)
Summary:
Due to oclif’s structure, this entry point shares its `commands`
directory with that of the V1 entry point. We’ll therefore add commands
like `start-v3` as we go.

Test Plan:
`yarn backend` works, and `node bin/sourcecredV3.js start` launches the
V1 server.

Copy graph-independent V1 Git plugin code to V3 (#401)
Summary:
Many files are unchanged. Some files have had paths updated, or new
build/test targets added.

The `types.js` file includes payload type definitions. These are
technically independent of the graph abstraction (i.e., nothing from V1
is imported and the code all still works), but it of course implicitly
depends on the V1 model. For now, we include the entirety of this file,
just so that we have a clean copy operation. Subsequent commits will
strip out this extraneous code.

Suggest reviewing with the `--find-copies-harder` argument to Git’s
diffing functions.

Test Plan:
Running `yarn travis --full` passes. Running

    ./src/v3/plugins/git/demoData/synchronizeToGithub.sh --dry-run

yields “Everything up-to-date”.

Fork project to v1/ and v2/ in preparation for v3 (#327)
We want to reset some of our basic assumptions, and make `Graph` into a
pure graph implementation, rather than a hybrid graph and key-value
store.

This is a substantial rewrite, so we want to start from scratch in a v3/
directory and pull code into v3 as necessary. So that we can do this in
a relatively clean fashion, we're first moving the v1 and v2 code into
their own directories.

Paired with @wchargin

Test plan:  Travis, and `yarn backend`, `node bin/sourcecred.js start`.

Note that `yarn backend` and `node bin/sourcecred.js start` both use the
v1 versions. We'll migrate those (by changing paths.js) to v3 when
appropriate.

Generate `bin/` in-place for cron CI (#325)
Summary:
This fixes a bug introduced in #317, which only occurred in the cron job
variant of the CI script (`yarn travis --full`): the two scripts run in
the cron job depend on `yarn backend` having previously written to the
`bin/` directory, but this is precisely what we wanted to prevent. To
fix this, we simply add an additional target for `yarn backend` during
the cron job. This is a little bit wasteful in that we compile the
backend applications twice, but it’s not a big deal because (a) it only
runs in cron jobs, so it won’t slow down normal builds, and (b) it only
takes about 5 seconds, anyway.

Test Plan:
Export a `GITHUB_TOKEN` and run `yarn travis --full`, which fails before
this change and passes after it.

Don’t erase the `bin/` folder in CI (#317)
Summary:
Previously, our CI script would run `yarn backend`, which has the
side-effect of erasing the `bin/` directory. By itself, this is not
great, but not awful. However, this frequently triggers a race condition
in Prettier, causing the `check-pretty` step of the build to fail. (More
details: https://github.com/prettier/prettier/issues/4468.)

This patch changes the CI script to build the backend scripts into a
temporary directory.

Test Plan:
Before applying this patch: `yarn backend` and then `yarn travis`. If
this consistently causes a Travis failure due to `check-pretty`, then
your machine can reproduce the race condition that we‛re trying to
eliminate. (Otherwise, you can try creating a bunch more Git history…
I’m not really sure what to say. It is a race condition, after all.)
Then, apply this patch, and repeat the above steps; note that the error
no longer occurs, and that the build output is to a temporary directory.

Flow: enable `//$ExpectFlowError` (#315)
As of this commit, adding the comment `//$ExpectFlowError` in flow-typed
code asserts that the next line must cause a flow error. If it does, no
error or warning is generated. If it does not, then this produces a flow
warning, which is visible to developers running `yarn flow` and
additionally causes travis to fail.

Test plan:

- As committed, `yarn travis` passes.
- I added `//$ExpectFlowError` above some line of flow-checked code which does
not currently throw an error. Afterwards, `yarn travis` failed (and a
helpful message was displayed in console on running `yarn flow`)
- I added the following bad code into one of our files:
```javascript
//$ExpectFlowError
const foo: string = 3;
```
As expected, `yarn flow` and `yarn travis` both passed.

Check for STOPSHIPs in CI (#301)
Summary:
Placing `STOPSHIP` or `stopship` (or any case variant) in any file
tracked by Git will now cause a `yarn travis` failure. If you need to
use this string, you can concatenate it as `"stop" + "ship"` or
equivalent.

Test Plan:
In `travis.js`, change `"check-stop" + "ships"` to `"check-stopships"`,
and note that this causes the build to fail with a nice message. Note
that this also causes `check-stopships.sh` to fail even when invoked
from an unrelated directory, like `src`.

Upgrade Flow to v0.72.0 (#285)
Summary:
A few changes were made to code that is correct (as far as I can tell),
but for which Flow can no longer infer a type parameter. The change is a
bit more annoying than it otherwise would be, because this particular
file is run directly via node and so must use Flow’s comment syntax for
type annotations, but Prettier breaks such comments in the cases that we
need. We work around this by rewriting the original code to avoid the
need for comments.

Test Plan:
In addition to standard CI, run `yarn build` and then run a server from
`build/`, to see that the production build produces a working bundle.
(That the app loads and renders is sufficient.)

Add `sourcecred start` (#234)
Summary:
We need a way for our web applications to interact with data on the
filesystem. In this commit, we introduce a webserver that serves
statically from two directory trees: first, the result of a live-updated
Webpack build; second, the SourceCred data directory.

Test Plan:
Run `yarn backend` and `node ./bin/sourcecred.js start`. When ready,
navigate to the server’s root route in a web browser. Note that a nice
React app is displayed. Then, change something in that React app source.
Note that the server console displays Webpack’s update messages, and
that refreshing the page in the browser renders the new version of the
app. Finally, visit

    /__data__/graphs/sourcecred/example-github/graph.json

in the browser to see the graph for the example repository, assuming
that you had generated its graph previously.

Implement a command-line interface (#217)
Summary:
This commit implements the `sourcecred` command-line utility, which has
three subcommands:
  - `plugin-graph` creates one plugin’s graph;
  - `combine` combines multiple on-disk graphs; and
  - `graph` creates all plugins’ graphs and combines them.

As an implementation detail, the `into.sh` script is very convenient,
avoiding needing to do any pipe management in Node (which is Not Fun).
When we build for release, we may want to factor that differently.

Test Plan:
To see it all in action, run `yarn backend`, and then try:
```
$ export SOURCECRED_GITHUB_TOKEN="your_token_here"
$ node ./bin/sourcecred.js graph sourcecred sourcecred
Using output directory: /tmp/sourcecred/sourcecred

```
The `node sourcecred.js graph` command takes 9.8s for me.

(The salient point of the last command is that the two small graphs have
node count adding up to the node count of the big graph. Incidentally,
we are [almost][1] at a nice round number of nodes in the GitHub graph.)

Target latest Node for backend applications (#213)
Summary:
Consequently, Babel won’t transform classes to their roughly equivalent
ES5 counterparts, etc.

Test Plan:
Create `src/classy.js` with `class X {}; console.log(X);`. Then, add a
build target for `classy: resolveApp("src/classy.js"),` in `paths.js`.
Use `yarn backend` and inspect the contents of `bin/classy.js`; in
particular, look at the definition of `X` (whatever the argument to
`console.log` is). Before this commit, the result will be a big
complicated mess. After this commit, it will be `class X {}`.

Note also that `yarn travis --full` passes, indicating that the two
manual tests, which call out to the utilities in `bin/`, still work.

object graph for that repository.

This can be run as follows:

This commit also adds two utility modules:
* `cloneAndLoadRepository` , which clones a Git repository to a tmpdir,
parses the `Repository` data out, and then cleans up.
* `cloneGitGraph`, which calls `cloneAndLoadRepository` and `createGraph`

network access to clone repositories from GitHub. I verified that the
functions work via the demo script above.

Summary:
This could catch failures in build configuration or with Webpack. It’s

In any case, it’s fast enough; it finishes at about the same time as

Run npm scripts with `--silent` in CI (#191)
Summary:
This prevents the boilerplate output of the form
```

> sourcecred-explorer@0.1.0 check-pretty /home/wchargin/git/sourcecred
> prettier --list-different '**/*.js'

```
(superfluous linebreaks included). In the case that a script fails, it
also omits the giant “this is most likely not a problem with npm” block.

The downside to this is that it suppresses any errors in npm-run-script
itself. For instance, `npm run wat` produces “missing script: wat”,
while `npm run --silent wat` just silently exits with 1. This does not
silence the actual scripts themselves, so things like lint errors or
test failures will still appear.

Test Plan:
Run `yarn travis` before and after this commit, and note that the
resulting build log is prettier after.

Implement a custom CI script (#189)
Summary:
This CI script accomplishes two tasks:
 1. It speeds up our build by parallelizing where possible.
 2. It opens the possibility for running Travis cron jobs.

Currently, this script by default does the same amount of work as our
current CI script. However, I’d like to move `yarn backend` into the
list of basic actions: a backend build failure should fail CI.

Note: this script is written to be executable directly by Node, so we
can’t use Flow types with the standard syntax. Instead, we use the
comment syntax: https://flow.org/en/docs/types/comments/

Test Plan:
The following should pass with useful output:
  - `npm run travis`
  - `GITHUB_TOKEN="your_github_token" npm run travis -- --full`

The following should fail with useful output:
  - `npm run travis -- --full` (fail)

To test different failure modes, it can be helpful to add
```js
    {id: "doomed", cmd: ["false"], deps: []},
    {id: "orphan", cmd: ["whoami"], deps: ["who", "are", "you"]},
```
to the list of `basicTasks` in `travis.js`.

To test performance:
```shell
$ time node ./config/travis.js >/dev/null 2>/dev/null

real    0m8.306s
user    0m20.336s
sys     0m1.364s

$ time bash -c \
>     'npm run check-pretty && npm run lint && npm run flow && CI=1 npm run test' \
>     >/dev/null 2>/dev/null

real    0m12.427s
user    0m13.752s

Two reasons for this. First, we want tests to be able to operate on this
data without having to generate repositories via `git(1)`. (Doing that
is slow, and requires a Git installation, and makes it less clear that
the tests are correctly isolated/provides more surface area for
something to go wrong.) Second, in general plugins will need a canonical
source of test data, so setting/continuing this precedent is a good
thing.

Test Plan:
Observe that the old Jest snapshot must be equivalent to the new JSON
one, because the test criterion in `loadRepository.test.js` changed and
the test still passes. Then, run `loadRepositoryTest.sh` and note that
it passes; change the `example-git.json` file and note that the test
fails when re-run; then, run the test with `--updateSnapshot` and watch
it magically revert your changes.

Add a command-line script to create example repos (#155)
Summary:
We’ll use this to create the repositories on disk and then push them to
GitHub.

Test Plan:
Generate both kinds of repository, and check out the SHAs:
```shell
$ yarn backend
$ node bin/createExampleRepo.js /tmp/repo
$ node bin/createExampleRepo.js --submodule /tmp/repo-submodule
$ node bin/createExampleRepo.js --no-submodule /tmp/repo-no-submodule
$ # (first and third lines do the same thing)
$ git -C /tmp/repo rev-parse HEAD
677b340674bde17fdaac3b5f5eef929139ef2a52
$ git -C /tmp/repo-submodule rev-parse HEAD
29ef158bc982733e2ba429fcf73e2f7562244188
$ git -C /tmp/repo-no-submodule rev-parse HEAD
677b340674bde17fdaac3b5f5eef929139ef2a52
```
Then, note that these SHAs are expected per the snapshot file in
`exampleRepo.test.js.snap`.

Make GitHub capitalization consistent within code (#100)
* Make GitHub capitalization consistent within code

We now never capitalize the H in GitHub within variable or function
names. We still capitalize it in comments or user facing strings.

Test plan:
Unit tests, the fetchGithubRepoTest.sh, and
`git grep itHub` only shows comment lines and print statements.

Repurpose React app as artifact editor (#89)
Summary:
We’ll now start creating the artifact plugin. A large part of this will
be the user interface, including a GUI. For now, our build system just
builds a single React app, so we’re cannibalizing the main explorer to
serve this purpose.

Paired with @dandelionmane.

Test Plan:
The following still work:
  - `yarn test`
  - `yarn start`
  - `yarn build; (cd build; python -m SimpleHTTPServer)`

Configure Webpack for backend applications (#84)
Summary:
Running `yarn backend` will now bundle backend applications. They’ll be
placed into the new `bin/` directory. This enables us to use ES6 modules
with the standard syntax, Flow types, and all the other goodies that
we’ve come to expect. A backend build takes about 2.5s on my laptop.

Created by forking the prod configuration to a backend configuration and
trimming it down appropriately.

To test out the new changes, this commit changes `fetchGitHubRepo` and
its driver to use the ES6 module system and Flow types, both of which
are properly resolved.

Test Plan:
Run `yarn backend`. Then, you can directly run an entry point via
```
$ node bin/fetchAndPrintGitHubRepo.js sourcecred example-repo "${TOKEN}"
```
or invoke the standard test driver via
```shell
$ GITHUB_TOKEN="${TOKEN}" src/backend/fetchGitHubRepoTest.sh
```
where `${TOKEN}` is your GitHub authentication token.

Move package json to root (#37)
Reorganize the code so that we have a single package.json file, which is at the root.
All source code now lives under `src`, separated into `src/backend` and `src/explorer`.

Test plan:

- run `yarn start` - it works
- run `yarn test` - it finds the tests (all in src/explorer) and they pass
- run `yarn flow` - it works. (tested with an error, that works too)
- run `yarn prettify` - it finds all the js files and writes to them
