Common superclass for all Transition Engines. A TransitionEngine handles transitioning into and out of
a
RouteNodeInstance . The TransitionEngine is also responsible for determining if a Node has completed.

Tell the WorkflowEngine processing the activeNodeInstance if the node is complete and transitionFrom can
be called.
Parameters: activeNodeInstance - boolean
Determines the next nodes instances for the transition. If the node instance already
has next nodes instances (i.e. a dynamic node), then those will be returned. Otherwise
it will resolve the next nodes from the RouteNode prototype.
