 /**
  * Add a state. without a transition.
  * Normally, you would not use this method directly but instead use
  * addTransition to add the transitions with the states in one go.
  * 
  * This method makes sense if you would want to load the statemachine with states
  * and not transitions, and then add the transitions with regex states.
  * This saves you the hassle of adding transitions before you add the
  * regex transitions (just so the states are already known on the machine).
  * 
  * in case a State is not used in a Transition, it will be orphaned and not 
  * reachable via other states.
  *
  * @param State $state 
  * @return boolean true if the state was not know to the machine or wasn't added, false otherwise.
