[Chart] Contour Plots and Darcs

[Sacha Sokoloski]

I'm glad you're interested. I'll wrap a patch up in the next little 
while and send it with tests and such. I'll probably want to implement a 
heat map at some point too, but that will take a bit longer.

As far darcs vs git, I do prefer darcs for smaller projects as well. 
Perhaps trying darcshub would be a good idea? I like the idea of 
supporting these projects.
