Ruby

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

StateMachine::NodeCollection#each

Calls the block once for each element in self, passing that element as a
parameter.

  states = StateMachine::NodeCollection.new
  states << StateMachine::State.new(machine, :parked)
  states << StateMachine::State.new(machine, :idling)
  states.each {|state| puts state.name, ' -- '}

...produces:

  parked -- idling --
