pythonizing initial review

Pythonizing initial review: Q4 2019

As of December 11, 2019, the Pythonizing group:

1. Finished Pythonizing the entire MPI doc (on the mpi-4.x branch)
2. Finished a 1st pass checking for correctness of the results

It is now time to ask the chapter committees to review our work and make sure of the following in your respective chapters (as compared to the mpi-4.x branch HEAD):

1. We Pythonized the bindings correctly: the generated PDF contains correct bindings
2. We didn't accidentally delete anything
3. We didn't accidentally add anything
4. We didn't accidentally edit anything

Note that there are acceptable LaTeX rendering differences between the mpi-4.x HEAD and the result of this work. See these slides (presented at the Dec 2019 MPI Forum physical meeting) to see the types of differences you can expect to see.

The slides also mention a tool you can use to help compare the LaTeX from the mpi-4.x HEAD to the Python-generated LaTeX on our pull request -- see this wiki page for instructions. This tool can greatly simplify your correctness check.
