IPython autojump magic

Written by keith hughitt <keith.hughitt@gmail.com>, based on an earlier

To install, `create a new IPython user profile <http://ipython.org/ipython-doc/stable/config/ipython.html#configuring-ipython>`_
if you have not already done so by running:

    ipython profile create

And copy this file into the "startup" folder of your new profile (e.g. 
"$HOME/.config/ipython/profile_default/startup/").
