WFP,

I was trying to think of some additional way to lay things like this out for
clarity, and I wondered if you might think about a way to evaluate functions in
a structure like a color_map.

Or perhaps more like a prism or a spline.

Then it would be easy to see what ranges any given function would be evaluated
in.

function_map {
     [0.0 FunctionA (x, y, z)]
     [0.3 FUnctionA (x, y, z)]
     [0.3 FunctionB (N)]
     [0.7 FunctionC (j, k)]
     [0.7 FunctionD (clock)]
     [1.0 FunctionD (clock)]
}

What are your thoughts on this type of data structure and how much work would
require its implementation?

- BW
