rsunlight 0.4

NEW FEATURES

• API keys can be now be stored as both an env var and an option. (#54)
• Most outputs by default are data.frames, and use the dplyr::tbl_df style (#50)
• New function added cg_documents() for the Congressional documents route (#35)

MINOR IMPROVEMENTS

• rCharts dependency removed. This package is still not on CRAN, so this is
  simpler. In addition, CRAN wants all deps in a "mainstream" CRAN like repo. (#53)
• Started test suite (#32)
• Added ability to vectorize some parameters in some functions (#21)
• Added description of n parameter in the cw_dates() function man page (#2)
• Non base R functions are now explicitly imported, from methods and utils packages (#55)
• Set base URLs for each of the four Sunlight APIs in one place, less error prone in case they change their base URLs (#46)

BUG FIXES

• Fixed bug due to unconventional object ([) returned when no data found in some Sunlight API routes (#51)
• Bug fixes to bills functions (#42)
