Detailed Description

ColorRange is a ScalarsToColors object to define a color spectrum for a scalar range.

An optional vector of colors may be passed in at construction time. The range of colors will be mapped to the scalar range, and interpolation between the colors will be performed as necessary. By default, the color range will run Red-Yellow-Green-Cyan-Blue.
