 /**
  * set the context on the statemachine and provide bidirectional
  * association.
  *
  * change the context for a statemachine that already has a context.
  * When the context is changed, but it is for the same statemachine (with
  * the same transitions), the statemachine can be used directly with the
  * new context.
  *
  * The current state is reset to whatever state the machine should be in
  * (either the initial state or the stored state) whenever a context change
  * is made.
  *
  * we can change context to:
  * - switch builders/persistence adapters at runtime
  * - reuse the statemachine for a different entity so we do not
  * have to load the statemachine with the same transition definitions
  *
  * @param Context $context            
  * @throws Exception
