// EXTENDED FLASH CHECK - amends by asmiller
//
// Script defaults to check for flash 4 as before
//
// Extended Feature -- HasFlash -- Ability to check for other versions pass version num as optional argument i.e. 
// -- HasFlash(7);
// Will return true or false
//
// Extended Feature -- insertFlash -- Ability to pass to flash a query string as optional argument i.e.
// -- InsertFlash( 'myFlash.swf', 300, 300, '#ffffff', 'myValue=someValue&myValue2=someOtherValue' );
//
// Extended Feature -- WriteFlashToContainer -- Ability to pass to flash a query string as optional argument i.e.
// -- WriteFlashToContainer( 'myFlash.swf', container, 300, 300, '#ffffff', 'myValue=someValue&myValue2=someOtherValue' );
