IntCachedColorMap

class IntCachedColorMap extends ColorMap

Caches a color ramp based on a histogram of values. This is an optimization, since often times we create a histogram while classifying, and can reuse that computed information in the color mapping.

In order for this class to work correctly the histogram acts as a map from values to their colors and must contain a value for each pixel value that we expect to encounter.

The performance benefit is eC lookup cost instead of Log provided by IntColorMap
