Several things:
    - Added James' skewed view to the default camera angles
    - Reworked how camera angles are processed in similar manner to James' method: everyhting is relative to box size and in degrees.
    - Added a parameter to capture output or display on screen, as part of Render_Parameters.py. It's not ideal, but debugging by typing less Gamma_*[tab]*blah.txt gets annoying.
    - Added what will be my keyframe timer, which I suspect may reveal that blender's scene setup time increases superlinearly with keyframe number.
