## Detailed Description

This map assigns one of the predefined Colors to each `int`. It is possible to change the colors as well as their number. The integer range is cyclically mapped to the provided set of colors.

This is a true reference map, so you can also change the actual colors.

Constructor.

Parameters

  have_white | Indicates whether white is among the provided initial colors (`true`) or not (`false`). If it is true, white will be assigned to `0`.
  num | The number of the allocated colors. If it is `-1`, the default color configuration is set up (26 color plus optionaly the white). If `num` is less then 26/27 then the default color list is cut. Otherwise the color list is filled repeatedly with the default color list. (The colors can be changed later on.)
