adaptive sampling for plotting of surfaces

[krastano...@gmail.com]

Just a quick suggestion if someone feels like doing it.

There is a relatively new function in matplotlib that permits plotting
triangular meshes. This is exactly the feature that was blocking the
creation of adaptive sampling methods for the plotting module. If
someone is interested to do it, you can get some inspiration from
https://github.com/sympy/sympy/pull/1388 in which Bharath implemented
a nice adaptive sampler for line plots.

to plot the contour projection of the surface
http://matplotlib.sourceforge.net/api/axes_api.html?highlight=contourf#matplotlib.axes.Axes.tricontourf

3d projections do not work yet

At some point we should think about using Mayavi as a 3d backend. It
is light-years ahead of matplotlib and what I would consider "the
standard solution for 3D plots in python"

Nice!! I will have a try once I am done with gsoc.

Yeah we should move to mayavi for 3d plots. 3d plots 

look way nice in mayavi.

But we should still offer matplotlib based 3D plotting
