matplotlib Code

- Fixes to main book so it compiles to PDF directly from LyX, without having
to use the kludgy lyxport script at all.

- Update some of the examples with minor fixes.

- Add new workbook directory. For now, I added the .tex files as well,
though they are generated from LyX, so John can use the system without LyX
while I'm gone. Once I'm back, we can decide how to best do this in the
long run.

added ellipse compare script

regenerated with cython 0.9.6.7

More progress on examples.

Forgot the __init__.py

First pass through all of the examples -- not all working yet,
though. (See PASSED_DEMOS).

fix typo

Fixed minor import bug

Continued progress getting more examples to work. Working examples
(with TkAgg backend only) are marked in PASSED_DEMOS for the curious.
