/*
	This Parentable Class is the base class for all other classes here - including
	both Atoms and Descriptors.  This allows the maintenance of the tree structure
	where every element has a parent - and that parent has three methods, getParent(),
	setParent(), and recomputeSize().  This allows the classes to recompute the size
	of their parent class when a child class is changed or added to.
