The Pandas and matplotlib api's are evolving. Pandashells
was throwing a bunch of deprication warnings and not all tests
were passing with the latest versions of these libraries. This
is basically a maintenance release to accomodate these changes.
Below are the highlights.
* Current versions are: pandas==0.17.1, matplotlib 1.5.1
* Fixed a bug in writing html tables
* Improved the Timer() profiling tool and added it to the docs.
