- Add \_get_max_nout and alternative nout mode using 'max_nout'
(170)

- FIX: no-OUT-args check was destroying original error location and
was hiding similar user-errors (161)

\- Removed the `executable` argument to `Oct2Py` in favor of using
environment variables because we need to instantiate the `octave`
convenience instance at startup.

- Add a plot_backend kwarg for eval and clean up default backend
selection.

- Add support for Pandas DataFrames and Series (125)
- Remove unwanted octave-workspace files at exit (133)
