Instead of creating a Transition per relation, maintain a MultiRelationalTransition

[GoogleCodeExporter]

The current code creates a Transition instance for each relation between two 
event instances. However, this is inefficient since these event instance 
transitions are never split out, and should really be maintained in a single 
object (e.g., so that we could query the set of all relations that are incident 
on an event instance).

Change the code to turn Transition into an abstract class, and add two new 
transition types -- SingleRelationTransition and MultiRelationalTransition. 
These new types should extend Transition and maintain a single relation 
reference or references to multiple relations (where relations are Strings).
