Message:

add alternative configuration for reference image so we can run diff with two different cameras (recipes from first image camera are used); remove commented out test lines and move test function to end of ppSubLoop.c; move bit of code to remove extra detection block into ppSubReadoutInverse to clean up the ppSubLoop flow
