 BASE -------> ACTR
																														
 Each actor has a unique route which is defined by one or more nodes,
 and which may be a concatenation of one or more subroutes.
 Each actor also has an event list describing events which happen
 at a specified time and point along the route.  A point may coincide
 with a node or lie between nodes.
