* Update the provided resource change description factory so it can
	 * generate a resource delta describing the result of an undo or redo.
	 * Return a boolean indicating whether any update was done. The default
	 * implementation does not update the factory. Subclasses are expected to
	 * override this method to more specifically describe their modifications to
	 * the workspace.
	 * 
	 * @param factory
	 *            the factory to update
	 * @param operation
	 *            an integer indicating whether the change is part of an
	 *            execute, undo, or redo
	 * @return a boolean indicating whether the factory was updated.
