Similar to the well known colorbarf but more realistic.
There are two things missing in colorbar and colorbarf:
1. the colorbar ticks are scaled according to the size of each interval.
2. when color is saturated at the upper limit, or when is white, below the lower limit, a triangle is added. The triangle means "more/less than". Such information is not provided by the existing tools, colorbar and colorbarf.
See the examples.
Besides, there is a bug (?) with contourf: in some cases, even with the levels specified, one additional level is added and corrensponds to the sourrounding line! In such case, colorbarf adds one box for this fake level!
