Expose DMPlexGetAdjacency

[Francesco Caimmi]

Would be a nice addition, since most of the other Adjacency routines have been already exposed.

Wow, that's fast! ;) Thank you very much. However install fails: I am doing

$git clone  https://bitbucket.org/petsc/petsc4py 
$git branch                                                                                                           
* master
$cd petsc4py
$python setup.py install

which fails with the following output https://drive.google.com/open?id=0ByT4soc3PmzVT053VGdjZl8xQTg

The branch petsc4py/master should be used with petsc/master. Are you using a release version or PETSc, or the petsc/maint branch? In that case, you cannot use my last commit. I have to cherry-pick the commit to the petsc4py/maint branch, and you must switch to that branch.

I was using petsc maint branch, using petsc4py/maint now compiles without issues. Thank you very much.

I checked the results from dm.getAdjacency() using the mesh generated by PETSc.DMPlex().createBoxMesh(2) and the results are the expected ones.
