/* switch infobox code for infoboxes
 * contains switching code for both:
 * * originalInfoboxes:
 *		older infobox switching, such as [[Template:Infobox Bonuses]]
 *		which works my generating complete infoboxes for each version
 * * moduleInfoboxes:
 *		newer switching, as implemented by [[Module:Infobox]]
 *		which generates one infobox and a resources pool for switching
 * * synced switches
 *		as generated by [[Module:Synced switch]] and its template
 * 
 * The script also facilitates synchronising infoboxes, so that if a button of one is pressed
 *	and another switchfobox on the same page also has that button, it will 'press' itself
 * This only activates if there are matching version parameters in the infoboxes (i.e. the button text is the same)
 * - thus it works best if the version parameters are all identical
 * 
 * TODO: OOUI? (probably not, its a little clunky and large for this. It'd need so much styling it isn't worthwhile)
