Ruby

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

StateMachine::Callback#run_methods

Runs all of the methods configured for this callback.

When running +around+ callbacks, this will evaluate each method and
yield when the last method has yielded.  The callback will only halt if
one of the methods does not yield.

For all other types of callbacks, this will evaluate each method in
order.  The callback will only halt if the resulting value from the
method passes the terminator.
