DONE		Sub LSystem support through ~ operator

DONE		Broke axiom specifing values that map to variables for subsequent rules.
				Some expressions not getting mapped to values forwarded in from predicate or state? progressiveRotation.ls demonstrates problem.
				Has something to do with using referenced compiled lsystems.
				Fix was the compiled systems contained intermediate symbols that referenced other rules.
