    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.
