  37 *       MarketUploader initializes after the main YPP window has initialized. It
  38 *       provides a simple window with a "Capture Market Data" button displayed.
  39 *       Upon clicking this button, a progress dialog is displayed, and the data
  40 *       is processed and submitted to the Pirate Commodities Trader with Bleach (PCTB)
  41 *       web server. If any errors occur, an error dialog is shown, and processing
  42 *       returns, the button becoming re-enabled.
