runToCompletion() public method

when using cyclic graphs, you could get into an infinite loop between states. design your machine correctly.
public runToCompletion ( string $message = null ) : integer
$message string optional message. this can be used by the persistence adapter to be part of the transition history to provide extra information about the transition.
return integer the number of sucessful transitions made.
