#28 Add disk/cpu heatmaps

[David Wright]

Looking at lots of cpus or especially disks is easiest with a heatmap. I have systems with lots of cpus and thousands of disks and they use ksar already.

http://www.mbeckler.org/heatMap/javadoc/index.html?HeatMap.html

Each dot would represent the device with colors indicating what it is doing.
For Cpus, if sys> 35 red, if usr > 35 blue, if wio > 35% cyan
FOr disks, a heatmap for Each column and color/threshold settings

I am not a programer so would need alot of help.
