//           script         - location of the serverside AJAX file to use; default = jqueryFileTree.php
//           folderEvent    - event to trigger expand/collapse; default = click
//           expandSpeed    - default = 500 (ms); use -1 for no animation
//           collapseSpeed  - default = 500 (ms); use -1 for no animation
//           expandEasing   - easing function to use on expand (optional)
//           collapseEasing - easing function to use on collapse (optional)
//           multiFolder    - whether or not to limit the browser to one subfolder at a time
//           loadMessage    - Message to display while initial tree loads (can be HTML)
