Make App Scaffold

[jbenet]

• single-page React app, all client-side
• make the home route

---

the routes will look like this:

/  - home, bit of info on depviz. lets you enter/paste an address to visualize.

/http/github.com/<user>/<repo>/issues/<issue> - viz single issue, + 2-3 hops
/http/github.com/<user>/<repo>/pull/<pr>      - viz single issue, + 2-3 hops
/http/github.com/<user>/<repo>                - try to visualize the whole graph of a repo?

• We use /http prefix to ensure we can use other protocols later.
• We use /http/github.com prefix to ensure we can use other websites later.
• We use /http/<github-link-to-thing> to match their API well and allow users to easily paste links.
