Takes most of the grunt work out of translating a numerical-tours
matlab file into an ipython notebook. It will auto-populate the
notebook with headings, markdown, code, and exercises as appropriate.
Ideally, all one then has to do is translate the code itself.
Some code transformations are in place (see CODE_REPLS and _parse_code
in this file).
