Got the basic features passing for review. Stuff may change on discussion though!
Added error handling and changed naming
Testing updates happen and making sure newer content isn't overwritten
Changed to use master version of capsulecrm
Added Gemfile.lock
Cleaned up cassettes
Added DATETIME transform to steps
Changed documentation to represent the current state of play

Third parameter in SendDirectoryEntryToCapsule.perform is now a string, rather than a DateTime object
