CoReg:
- get_clip_window_properties():
    - now fully supports rectangular matching windows and properly outputs the aimed window sizes
    - the matching window size is automatically decreased if image overlap is too small
    - algorithm/code heavily facilitated by adding a self-updating boxObj representing the matching window
- removed deprecated versions of get_clip_window_properties()

GEO:
- added class boxObj: a dynamic/self-updating box object for representing rectangular vector boxes
- added converter functions shapelyImPoly_to_shapelyMapPoly_withPRJ(), shapelyImPoly_to_shapelyMapPoly()

IO:
- fixed a missing function reference in init_SharedArray_on_disk()
