    This application gathers info from the WZ.XML files, fetching all cosmetic coupons and tickets from there, and then
    searches the NPC script files, identifying the stylish NPCs that supposedly uses them. It will reports all NPCs that
    uses up a card, as well as report those currently unused.
   
    Estimated parse time: 10 seconds
