Ruby

Adds support for creating state machines for attributes on any Ruby class

StateMachine::State#final?

Determines whether there are any states that can be transitioned to from
this state.  If there are none, then this state is considered *final*.
Any objects in a final state will remain so forever given the current
machine's definition.
