Detailed Description
--------------------


   
   Progress indication class for different complex operations which might take a long time
   (e.g. rendering, exporting, etc.).
   
   There are 4 main Qt signals:
   
   * `started()`: The signal being emitted when operation starts.
   * `progress_status(int)`: The signal being emitted during operation.
   * `progress_message(unicode)`: Verbose signal being emitted during operation.
   * `finished()`: The signal being emitted when operation ends.
