Banyan: App for visualizing Dropbox file and directory sizes

[mattpiz]

@osteele

Challenges included wrapping my head around encoders (easy) and decoders (hard); figuring out whether and which CSS/UI framework to use (I made several false starts); learning how to use a forked package (so that I could use my changes to elm-dropbox while I was still preparing PRs and then waiting for their acceptance); finding the intersection between the record update and pattern matching syntax that I expected to work and what actually did; and finding and evaluating visualization libraries. A deeper challenge was figuring out best practices for structuring a larger application. The structure started to get away from me a couple of times, and I had to wrangle it back through ad-hoc refactoring: I think Elm lends itself to beautiful code, but my Elm code is not currently beautiful.
