Test Plan:
This snapshot test is too unwieldy to actually read—it’s 1000 lines of
opaque SHAs and thrice-stringified JSON objects—so it should be
interpreted as a regression test only. The programmatic tests should
suffice.

Previously, the address module exported `sortedByAddress`, a utility
function that sorts an array of `Addressable`s. This function was only
used in test code.
This commit replaces it with generic usage of `lodash.sortBy`. This
reduces the API surface area of the module, and removes test-only code
from the exported api.
New dependency added: `lodash.sortby`
https://www.npmjs.com/package/lodash.sortby
Summary:
This commit moves our existing frontend tests to use Enzyme’s shallow
rendering API <http://airbnb.io/enzyme/docs/api/shallow.html>. The
benefit over also using `react-test-renderer` is simply consistency (the
two are functionally equivalent); the benefits over `mount` are that
subcomponents cannot contaminate the test state (i.e., you’re only
testing one component at a time), that the resulting snapshots are more
readable because the root props are not shown, and that the
implementation is more efficient. This is a follow-up to #102.
In a case where we actually need a full DOM tree, we should still feel
free to use `mount`, but we haven’t needed that yet.
Test Plan:
Verify that the new `ContributionList.test.js.snap` represents the same
data as the old one.
wchargin-branch: standardize-enzyme-shallow
Summary:
This is our first dynamic test of a React component! Enzyme looks pretty
easy to use to me, for both snapshot tests and interaction simulation.
In doing so, we catch a minor bug in the edge case where a contribution
is not owned by any plugin (`colSpan`, not `colspan`). This edge case
does not appear in the sample data, but it does appear in the test data,
even prior to this commit. The previous renderer, `react-test-renderer`,
appears not to surface this error. Furthermore, this bug did not cause
any user-visible errors except a `console.error`.
Test Plan:
Inspect the snapshot file to make sure that it is reasonable. (The
existing test case has its snapshot regenerated due to formatting
differences between the two renderers.)
To test that the browser error is fixed, render a contribution list on a
GitHub graph but with an empty adapter set. One way to do this is to comment out line 7 of
`standardAdapterSet.js`; alternately, you can use the React Dev Tools to
select the `ContributionList` node, then run
```js
$r.props.adapters.adapters = {};
$r.forceUpdate();
```
Note subsequently that there is no console error and that the `<td>`s in
question span three columns.
wchargin-branch: contributionlist-dynamic-test
Summary:
This commit begins to extend the artifact editor to display
contributions. To display contributions from arbitrary plugins, we need
to communicate with those plugins somehow. We do so via an adapter
interface that plugins implement; included in this commit is an
implementation of this interface for the GitHub plugin (partially: we
punt on rendering).
This includes a snapshot test. The snapshot format is designed to be
human-readable and -auditable so that it can serve as documentation.
Test Plan:
Run the application with `yarn start`. Then, fetch a graph and watch as
its contributions appear in the view.

Summary:
It’s a whole new world of GraphQL! Our parser is now just a GraphQL
query that asks for exactly what we want and dumps it to a file. The
data exposed by the v4 API is also in a much nicer format than that of
the v3 API, so this is pretty much a universal improvement.
Currently, we do not handle pagination. We require that the repository
in question have fewer than a fixed number of issues, and comments per
issue, and reviews per PR, and review comments per PR, and so on. If
this limit is exceeded, the script will fail-fast with a nice error
message. To fix this, we’ll need to write a general-purpose pagination
API that allows traversing cursors at any level of the query.
Paired with @wchargin.
Test Plan:
Run
$ GITHUB_TOKEN="your_token_here" src/backend/fetchGitHubRepoTest.sh
and verify that it exits with 0. Note that if you change this script’s
repository from `tiny-example-repository` to `sourcecred`, the script
correctly fails and outputs a useful diff.

Summary:
We need this for testing graph equality: deep-equality is not sufficient
because two graphs can be logically equal even if, say, two nodes are
added in different orders.
This commit adds a dependency on `lodash.isequal` for deep equality.
Test Plan:
New unit tests added. Run `yarn flow && yarn test`.

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
