require_tree argument must be a directory error

[wulftone]

I tried running part-5, and it complained about two missing directories:

#= require_tree ./Directives/main
#= require_tree ./Filters/main

Those aren't in your project (maybe they were never used!) I removed them from main.js.coffee and it seems to fix the problem. : )

had the same issue @wulftone fix works for me as well.
