-Matplotlib created a temporary cache directory at /tmp/codejail-hveq16ah/tmp/matplotlib-tv0c_vzt because the default path (/home/sandbox/.config/matplotlib) is not a writable directory; it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.

This makes it easier to run matplotlib in codejail, and should prevent a
number of other issues in the future with other packages that need to
create tempfiles.
No change is required for existing codejail installations, but after this
change operators may be able to tighten their apparmor configuration to
prevent write access to global temp or cache dirs.
Manual testing instructions: Create a codejail problem that runs
`import matplotlib` and confirm that it runs without error. (Unit tests
aren't feasible here because this requires a fully configured codejail in
order for the tmp subdirectory to exist.)
Also: Add comment for `OPENBLAS_NUM_THREADS` and numpy support.
* get rid of six.text_type(s)
* get rid of six.b()
* get rid of six.string_types
* get rid of six.PY2/six.PY3
* get rid of six.iteritems() and six.viewvalues()
As part of dissolving our sub-projects in edx-platform, we are moving this package under the xmodule directory.
We have fixed all the occurences of import of this package and also fixed all documents related references.
This might break your platform if you have any reference of `import capa` or `from capa import` in your codebase or in any Xblock.
