Ruby

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

StateMachine::MatcherHelpers#any

Represents a state that matches all known states in a machine.

== Examples

  class Vehicle
    state_machine do
      before_transition any => :parked, :do => lambda {...}
      before_transition all - :parked => all - :idling, :do => lambda {}
      
      event :park
        transition all => :parked
      end
      
      event :crash
        transition all - :parked => :stalled
      end
    end
  end

In the above example, +all+ will match the following states since they
are known:
* +parked+
* +stalled+
* +idling+
