// CSS Write Action Script 
// By Matt Ridley
//  Changes in version 1.1
//   * Now deals specifically with IE5 Mac
//   * Now allows choosing a StyleSheet for all other browsers (v4 or later)
//   * Now doesn't write a StyleSheet if the URL is "(Empty Reference!)"
// Modify for appropriate style sheet file names
