[petsc-users] PETSc recommended visualization packages

[Ethan Coon]

Attached patch takes Lisandro's matio.py and puts it in a
PetscBinaryRead.py that reads a binary with (potentially) multiple Petsc
objects, deciphers the contents of the file from the header, and returns
numpy objects.  It's basically the same as the PetscBinaryRead.m

I've tested this on Vecs, but not Mats or ISs, and I haven't thoroughly
tested degenerate cases.  Will do some testing, but I wanted Lisandro to
take a look at it as well...

Thanks,

Ethan

For things run on a reasonably-sized problem, matplotlib (using either h5py to read hdf5, pyvtk to read vtk, or petsc4py to read PETSc's binary format) makes publishable plots.
