Detailed Description

Color Sample Table used with vtkm::cont::ColorTable for fast coloring.

Holds a special layout of sampled values with the pattern of [Below Color, samples, last sample value again, Above Color, Nan Color ]

This layout has been chosen as it allows for efficient access for values inside the range, and values outside the range. The last value being duplicated a second time is an optimization for fast interpolation of values that are very near to the Max value of the range.
