Represents a GRASS rastermap color table.

Colortables for GRASS 5 and greater are supported.

Format of the color file, which is located in location/mapset/colr/mapname:

The first line is a % character and two numbers indicating the minimum and maximum data values which have colors. Note that in JGrass after the range values we add a third value for alpha support.

After the first line, the list of color rules appears, that can be of the following formats:

value1:r:g:b value2:r:g:b interpolation of colors between the two values with the two colors
value1:grey value2:grey
value1:r:g:b assumption that it means that value1 == value2
nv:r:g:b novalues could also have color with such a rule.
