  25 *       MarketUploader is a class that handles the uploading of market
  26 *       data from Yohoho! Puzzle Pirates via the Java Accessibility
  27 *       API.
  28 *
  29 *       MarketUploader initializes after the main YPP window has
  30 *       initialized. It provides a simple window with a "Capture
  31 *       Market Data" button displayed.  Upon clicking this button, a
  32 *       progress dialog is displayed, and the data is processed and
  33 *       submitted to the YARRG and PCTB servers. If any errors occur,
  34 *       an error dialog is shown, and processing returns, the button
  35 *       becoming re-enabled.
