// I made this script (adapted from mmmturkeybacon's Export Mturk History), because on mturk.com, your qual list is only 
// sortable by qual name. To use this script, go to the "Qualifications Assigned To You" page. Click the Start button.
// It generates a list of all your currently assigned quals. When it finishes running, select all the output in the
// text box, and copy it into a spreadsheet. Then you can sort and filter as desired, using your spreadsheet program's
// functionality - for example, to see which quals you most recently received, or all quals from a certain requester.
// And if you save copies of past versions of the output list, you can compare them in the future to see changes if desired.
 
 
 
// check if you're on the "Qualifications Assigned To You" page, so you don't think you can run this on the huge list of all quals
