Title: Removed stray code for measuring a hue map when there is only one Retina...

... (depends on other code that was never committed to the repository).

This reverts hue map measurement to how it was originally, before I started using a three-channel retina. (The problem is that I never committed that three-channel retina and related code - sorry!)
