Using Pyramids results in an error in the UI

[KevinMcGee]

The UI crashes when the user selects the pyramid option. This is because the pyramid step sizes are never set and results in this error:

terminate called after throwing an instance of 'cv::Exception'
  what():  /home/jwhite/src/DeepCoreDependencies/opencv-3.1.0/modules/core/src/matrix.cpp:508: error: (-215) 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows in function Mat

Aborted (core dumped)

For now, the pyramid option is being hidden until this issue is resolved. We need to add the ability for the user to set their pyramid step-size/window size in the UI for this to function properly.
