Detailed Description

Abstract base class for all state elements.

This is the abstract base class for all state elements. This class defines the following features for all of its derived classes:

<B> Type identifiers: </B> Each class of element has a unique (static)
SoType identifier. The correct type id is also stored in each
instance for easy access.

<B> Copying: </B> Elements are copied into the list of elements used
in an SoCache. Performing any operation other than matches()
on a copied element is not guaranteed to work (and will not
work for things like Coordinates, if the coordinate they were
pointing to has been deleted).

<B> Stack indices: </B> Since a subclass of an element class needs to
be in the same state stack as the class from which it is
derived, stack indices are inherited.

<B> Capturing: </B> Each time an element's value is accessed, that
element is added to the elements-used list of all currently
open caches.
