/*Custom version of the innerHTML.html script from the Asleson and Schutta book
Re-Scripted by David DuRocher for ADL, January, 2006

insource - the url of the page that is to be the source of information
inDestination - the ID of the container that the "insource" page will land in
inCaller - the id of the item that contains the value that is passed into the "searchInfo"
inHideContainer - supposed to be whether or not to hide the inDestination if it is blank
value - the value to pass in directly

Still in development
