   The CQLFactory class enables the user to construct and access complex CQL objects from simple objects without
   having to call each constructor or each getter in the CQL object tree.  

   Three uses:
	makeObject - allows the caller to pass in a CQL object and a target object type.  This returns the target type
		     built from the initial object.

	getObject  - allows caller to pass in a CQL object and target query object type.  This returns the target type 
		     contained within the CQL object passed in.
		     
	setObject  - allows caller to pass in a CQLPredicate, and object to set into the CQlPredicate and its type.
