Take Flight!

[Flight](https://flightjs.github.io) is a lightweight web framework that seems like it's a good fit for what Finda is trying to be.  I've spent a little time putting together a version which uses it to organize the various pieces.

I think it'll make it easier to develop and test different pieces going forward, and it also made it easy for me to support IE7 (which the current version didn't quite do).

You can see the results on my version: https://paulswartz.github.io/filter-template/
