/*

 initial concept by by Geoff Stearns (geoff@deconcept.com, http://www.deconcept.com/)
 i've updated it to be more reliant upon css, and have added some cross-movie functions

 added support for major and minor flash version requirements
 removed bypass text in lieu of just altTxt
 modifed constructor to include the bare necessities
 id property automatically created from the swf url string
 fixed the ie pc object tag to include the codebase tag
 creates div's on the fly if the div does not exist

 */
