• Added to_sym to State and Event.
• State#name and Event#name now return the string version of the name instead of the symbol version.
• Added State#human_name and Event#human_name to automatically figure out what the human name is if it isn’t specified in the table.
• Updated manual rollbacks to use the new Rails edge api (ActiveRecord::Rollback exception).
• Moved StateExtension class into a separate file in order to help keep the has_state files clean.
• Renamed InvalidState and InvalidEvent exceptions to StateNotFound and EventNotFound in order to follow the ActiveRecord convention (i.e. RecordNotFound).
• Added StateNotActive and EventNotActive exceptions to help differentiate between states which don’t exist and states which weren’t defined in the class.
• Added support for defining callbacks like so:

  def before_exit_parked end

  def after_enter_idling end

• Added support for defining callbacks using class methods:

  before_exit_parked :fasten_seatbelt

• Added event callbacks after the transition has occurred (e.g. after_park)
• State callbacks no longer receive any of the arguments that were provided in the event action
• Updated license to include our names.
