initial script commit

- script requires one argument: the directory of the course material
  (from the zip file from 2012books.lardbucket.org)
- script will parse the index.html file in that directory for
  information regarding chapters and sections within chapters
    - at this point, nothing is done with that information however
- script will create new course directory and add the basic index.md
  file for the course will the title and layout meta information
add requirements.txt
