viewing 3D Cahn-Hilliard is broken #115

Reported by Edwin.

I have been playing with FiPy all morning, mostly with the 1D and 2D examples. A few minutes ago, I started to play with the 3D viewers. I extended the 2D spinodal decomposition example and simply ran it (please find attached spinodal3D.py). Maybe I did something wrong, but upon running it, I got the warning:

Warning: The Mayavi viewer may or may not render 3D meshes correctly The method Mesh._getOrderedCellVertexIDs() needs to be fixed to return the correct ordering for 3D meshes that fits with pyvtk paradigm.

and the 3D mesh looks quite awkward (please see attached TIFF).

Fixed in r2626 by correcting the UniformGrid3D vertex numbering.
