/*
Overlay+Entry Script
Modified by: 		MetrixLab
Description: 		Script 
Latest update on: 	14-10-2005
29-09-2005: 		changed VBscript to JavaScript, made variables unique, added variable metrixlab_privacyLanguage
						reduced usage of hardcoded projectNumber variables
30-09-2005: 		changed loading of overlay: image is now loaded before the overlay is shown.
14-10-2005: 		changed extra variables. Shorter list to edit.
18-10-2005:		changed extra variables. Cookie survive and ForceData
14-12-2005:		combine the entry-exit technique
17-01-2006:		Insert an extra layer to avoid the problem with forms attributes and Flash objects
04-08-2006:		fixed critical bug in metrixlab_checkStartSurvey: onload and onabort event where wrong
						added metrixlab_startOverlay which dynamically adds the iframe, imagemap and div to the page via DOM
							Iframe widht and height are now set in metrixlab_loadOverlayCreative
						added metrixlab_onready which executes the script when the DOM is loaded (not the page, but sooner)
