A helper routine to generate a cmap and a norm instance whichbehave similar to contourf's levels and colors arguments.

Parameters:

levelssequence of numbers

The quantization levels used to construct theBoundaryNorm.Valuev is quantized to leveli iflev[i]<=v<lev[i+1].

colorssequence of colors

The fill color to use for each level. Ifextend is "neither" theremust ben_level-1 colors. For anextend of "min" or "max" addone extra color, and for anextend of "both" add two colors.
