 * Version:       1.0 (10-01-2007)
  * Works on:   Inernet Eplorer 6, Firefox 1.5
 * Description: Can detect flash version and if quitime is installed
 *                    Generates correct HTML for movie display
 *                    Can replace a HTML element with movie html
 *
 *
 * Usage:
 *		myMovie = new multiMovie("id", width, height);
 *     myMovie.addMovie("filename"); / supports mov, wmv, flv
 *     myMovie.write("htmlelementid"); // script puts movie html inside html element
