/**
==============================================================================
*	This file will show documents in a separate frame.
*	We don't like frames, but it was the best of two bad things.
*
*	display html files within Dokeos - html files have the Dokeos header.
*
*	--- advantages ---
*	users "feel" like they are in Dokeos,
*	and they can use the navigation context provided by the header.
*
*	--- design ---
*	a file gets a parameter (an html file)
*	and shows
*	- dokeos header
*	- html file from parameter
*	- (removed) dokeos footer
