//
// About: parses each file path in the playlist and copies each file to a folder on the user's desktop

// About: gets name from user in order to go to their desktop directory and get to their iTunes XML file 
// and asks for the name of the playlist to copy to folder on desktop
//
//
// Additional Note: requires that user has checked off option in iTunes to have XML file generated by iTunes.
