Cold Colormap

Creates a COLD colormap that complements the built-in HOT colormap

Description

COLD Black-Blue-Cyan-White Color Map

COLD(M) returns an M-by-3 matrix containing a "cold" colormap
COLD, by itself, is the same length as the current figure's colormap. If no figure exists, MATLAB creates one.
 
Example:
 imagesc(peaks(500))
 colormap(cold); colorbar
 
Example:
 load topo
 imagesc(0:360,-90:90,topo), axis xy
 colormap(cold); colorbar

You might add a see also for cool, an existing colormap with a slightly different shape in terms of colors.

Regardless, this adds another colormap option. As always, the help is what I'd expect.

I like your submission. Simple, well written code. Your example inspired me to make a similar one for my Perceptually improved colormaps submission.
