32 * MarketUploader is a class that handles the uploading of market data from
33 * Yohoho! Puzzle Pirates. Currently, it must be launched in the save Java
34 * Virtual Machine as YPP. This is handled by a sister "helper" class,
35 * {@link MarketUploaderRunner}.
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.
44 * @see MarketUploaderRunner
