-----DESCRIPTION: -----------------------------------
	Generate a JavaScript segment that automatically redirects the browser to
	the index page to enforce the use of frames. Used for frames that should
	never be viewed outside of the tech interface frameset.

	reload_index_nourl ignores the requested URL and redirects straight back
	to home/index.php.

	reload_index_frameset does the reverse and is used for tech/home/index.php;
	if the browser *is* in a frameset, break out and start it over again

-----RETURNS:----------------------------------------
	None; directly produces output.
