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”.

Port GitHub data ingestion into v3 (#378)
This commit copies the following logic necessary for downloading GitHub
data into v3. Minimal changes have been made to accomodate the new path
structure.

Test plan:
- Manually ran plugins/github/fetchGithubRepoTest.sh and verified that
it can correctly pass and fail
- Added the v3 github repo test to `yarn travis --full`
- Ran `yarn travis --full` and it passed

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.

Proxy Webpack dev server through to an API server (#245)
Summary:
This way, our frontend can talk to a backend that can read from the
filesystem (among other things).

Paired with @decentralion.

Test Plan:
```
$ yarn backend
$ SOURCECRED_DIRECTORY=/tmp/srccrd yarn start
$ # verify that the browser looks good
$ mkdir /tmp/srccrd
$ echo hello >/tmp/srccrd/world
$ curl localhost:3000/api/v1/data/world
hello
$ curl localhost:4000/api/v1/data/world
hello
```

Dandelion Mané 63351e6149 Move app scaffolding to src/app
This commit executes a micro-refactor to move all top-level app setup
code out of src/plugins/artifact/editor and into src/app. The observed
behavior from `yarn start`, which is to show the artifact editor, is
unchanged.

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.

Ensure that flow is used in all js files (#232)
This script ensures that either //@flow or //@no-flow is present in
every js file. Every existing js file that would fail this check has
been given //@no-flow, we should work to remove all of these in the
future.

Test plan:
I verified that `yarn travis` fails before fixing the other js files,
and passes afterwards.

Remove redundant scripts (#225)
Our SourceCred CLI tool now ipmlements printCombinedGraph and
cloneAndPrintGitGraph, but with more principled implementations and
interfaces :)

Test plan:
`yarn travis --full` passes, so I didn't delete any needed test infra.

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

Starting tasks
  GO   create-git
  GO   create-github
 PASS  create-github
 PASS  create-git
  GO   combine
 PASS  combine

graph-github.json  graph-git.json  graph.json

$ jq '.nodes | length' /tmp/sourcecred/sourcecred/*.json

7302
8302
```
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.)

Minimal toy oclif integration (#214)
This commit adds [oclif] as a command-line framework. It is successfully
integrated with webpack.

[oclif]: https://github.com/oclif/oclif

Usage:
`yarn backend` to build the cli.
`node bin/sourcecred.js` to launch the CLI and see usage
`node bin/sourcecred.js example` for one example command
`node bin/sourcecred.js goodbye` for another example command

Add `src/tools/bin/printCombinedGraph.js` (#207)
`printCombinedGraph` loads and prints a cross-plugin combined
contribution graph for a given GitHub repository.

It is a simple executable wrapper around `src/tools/loadCombinedGraph`.

Example usage:
`node bin/printCombinedGraph.js sourcecred example-git $GITHUB_TOKEN`

Add CLI for printing a fresh Git graph (#206)
`cloneAndPrintGitGraph` clones a git repository, and generates a Git
object graph for that repository.

This can be run as follows:
```
yarn backend;
node bin/cloneAndPrintGitGraph sourcecred example-git
```

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`

Test plan: These don't fit well into our CI, because they require
network access to clone repositories from GitHub. I verified that the
functions work via the demo script above.

Fix all lint errors, adding a lint CI step (#175)

Check in example repo’s in-memory representation (#166)
Summary:
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.

* Fix William's klaxon

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
