Test out inheritance for writing custom route matching code

[rictic]

This won't land until the extends branch in Polymer is merged, but we should test it out to be confident that this should work.

The test succeeded, now just waiting on inheritance to land in Polymer core.

Will this handle things like having one route handle:

• /start/
• /docs/
• /tools/

but not:

• /search/
• /api/

... because I can't figure out how to do that now.

@arthurevans You could definitely extend the route matching logic to support that use case.

Cool. I don't suppose you have any ideas for how we could do this now...? Asking for a friend. Or a friendly website.
