Adding a user viewing Look

user-look-base.ocio

The base config in this case is the ACES CG config: cg-config-v1.0.0_aces-v1.3_ocio-v2.1

user-look-input.ocio

user-look-merged.ocio

The primary differences is that the new look is added at the top of the looks section and the new view with the look is added as the first element in the shared_views section. The sRGB and Rec.709 displays are updated with the new view at the start of their Views element. The search_path includes the local (aka working) directory. The assumption is that the user's LUT file will be in the same directory as the merged config file. The name and description are updated to prevent any confusion with the merged config and the official CG config.

<   This minimalistic "OpenColorIO" config is geared toward computer graphics artists requiring a lean config that does not include camera colorspaces and the less common displays and looks.
