Captk unresponsive while calculating features

[eac-upenn]

#368 Actual Behavior

With an image and a valid ROI, from the Feature Extraction tab click Compute + Save. If the calculation takes any substantial time, the application displays the spinning blue ring and will grey out and become unresponsive if the user clicks within the Captk window.

Desired behavior

1. A dialog with a progress bar.
2. The application doesn't need to respond while calculating, but the greyed-out effect (I don't know the technical Windows UI term) doesn't inspire confidence. - Edit: The best solution might just to make the progress/Cancel dialog modal.
3. A Cancel button, in case I've accidentally started a huge calculation that I didn't actually want to do.

This is a generic issue for the GUI. The processing should be offloaded to a separate thread.
