/**
 *	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
