Several updates and bug fixes.

setup.sh

    Updated for new dependencies and new version of distribute.
    Currently, pandas 0.13.0 will not install,
    so added hack for pandas==0.12.0 until pandas folks make 0.13.0 work.

An-Introduction--Notebook-Features.ipynb

    Change path for image.

    The old image does not exist on fresh installs, 
    so I used a path that does exist.

    old: f = 'venv/build/scipy/doc/source/_static/scipyshiny_small.png'
    new: f = 'venv/lib/python2.7/site-packages/pyface/images/about.jpg'

    I don't know why the name of the notebook was made empty.
    It seems to work fine anyway.

An-Introduction--Pandas.ipynb

    Cleared output so that it would be generated from scratch like other
    notebooks.

Axis-Wobble.ipynb

    Added '%pylab inline' cell at top to fix missing output bug.

    I don't know why the name of the notebook was made empty.
    It seems to work fine anyway.

INSTALL-xubuntu-12.10

    Put in repository so that it does not get lost.
    Although it is correct only for Xubuntu 12.10, it gives other Linux
    users some clues to figure out the dependencies.
