// Notes on using this plugin

// DOES NOT PLAY WELL WITH FLASH!
// 1)  REMOVE ANIMATIONS WHEN USED IN CONJUNCTION WITH FLASH. NO FADE INS!
//     Transparency is okay, just do not animate it.
//     For the future. Make pluggin adaptable to whether or not flash is used.
// 2)  BE CAREFULL WHEN CREATING LIGHTBOXES WITH FLASH INSIDE.
//     It might look good, but ie6 looks aliased. Blocky.
//     The only way to do this succesfully is to not animate the box fading in.
//     Also you'll have to force the browser to recognize the box by doing
//     something inert like $('#container').css({dispaly: 'block'}), then use the swfobject code
// 3)  NO PNG'S IN INTERSTITIAL MESSAGE!
//     ie6 no likey
// 4)  Because of security uses. You'll have to test on a server and not your local.
//     Flash cannot call javascript locally. It can only do it online... unless I'm missing something?
// 5)  Okay.... IE8 is all wierdo. Apparently it doesn't like dynamically added elements (div's) with
//     transparent effects rendered on top of flash elements. It freaks out and crashes the browser.
//     The alternative is to decrease the opacity of the containing flash element to fake a mask div.
//     Its a little fuzzy to think about but it works.
