Added basic implementation of CamProjectDockWindow's settings area.  To see it in action add an Example CPP TPG.  Note: its not fully connected to the UI yet so it only shows settings when its added.
- Added save implementation for radio button settings.
- Suspect there is a memory corruption issue with the Example Plugin that causes a segfault occasionally.
Added progressbar section to CamProjectDockWindow
- Implemented the PyTPG API's (Geometry and Status updates)
- Modified Example Python TPG to use the added PyTPG API's
Cleaned up CamProjectDockWindow widgets
