	// Bath.co.uk Frame Checker v0.2
	//
	// This script checks to see whether or not part of the Bath.co.uk
	// website has been loaded outside of the frameset.  If it has, it 
	// automatically reloads the Bath frameset, then reloads the content
	// the user originally intended to go to.
	//
	// This is a two-stage process.  First, the script detects if the site
	// is not part of the normal frameset - and if it isn't, it reloads the
	// site with the target url stub appended (see array below)
	//
	// When the site loads and detects the frameset is correct, it checks to
	// see if there is a stub, and if there is it replaces the main content
	// with the target.
	//
