Features:
-view bills, legislators, good deeds
-bills link to legislators (and vice versa)
-good deeds link to bills, legislators, and related good deeds
-can pull bills and legislators from Sunlight API
-can create good deeds based on bill and legislator information
-good deeds are bills that were voted on or bills that were enacted
-API supports bills, legislators, good deeds; both individual and lists
-TDD tests (rspec)
-BDD tests (cucumber)
-basic user authentication

Missing:
-better testing
-user emails for new good deeds
-user tags on good deeds/other info
