NF: Starting to work on tools to convert m files into notebooks.
RF + TST: More work on matlab => notebook.

Including some basic tests.
RF: Some more futzing around with the 'publish' library.
RF: Some installation cleanup.
Added a matlab function to publish an m file into a matlab notebook in ipynb

This still doesn't quite work, because matlab path-setting is weird.
TST: Added testing of the publish module.
Make the package installable
Modified __init__.py so that publish is now importable
Added publish-notebook to installation
Set PYTHONPATH before calling publish-notebook in matlab
Cleanup
Merge pull request #58 from haoxingz/publish_from-matlab
