# NAME:
# class PageStack
#
# DESC:
# Implements a stack-like class for saving and recalling items
# like pages in a help browser. It differs from a traditional
# stack only by the 'back' and 'next' methods which move up and
# down the stack without disturbing it, unlike 'push' and 'pop'.
#
# NOTES:
# Currently used by the HtmlViewer class.
