AS3 Signal StateMachine for Robotlegs

An Signal driven StateMachine utility with six transition phases:

version 0.5.0

1. entering guard: Allows for testing of conditions to assess whether it is permissible to enter the target state. If not, the transition can be cancelled.
2. exiting guard: The first state-specific phase, it allows for testing of conditions to assess whether it is permissible to leave the current state. If not, the transition can be cancelled.
3. cancelled: Occurs if the transition is cancelled in either the entering guard or the exiting guard.
4. teardown: Occurs after the state has changed, but before the entered phase of the target state
5. entered: the final state-specific phase indicates that the transition to the new state has been successful.
6. changed: this post-transition phase sends a general notification that the state has changed.
