Multiple coloring effects

[LemurPwned]

3D display should have multiple coloring options that can be selected:

• [x] color palette
• [x] color switching point
• [x] new color metrics
• [x] custom color metrics

Updated color policy in the latest commit. Now only custom color metrics remain

This has already been wrapped up by adding decimation and vector sets in GUI already in #47
