Hi all,

Would anyone object to me updating the install script dependency and notebook dependency to IPython 4.x?

Right now it's quite annoying to edit the notebooks in the documentation, since you basically need to either edit them "by hand" (e.g. by directly editing the .ipynb file in a text editor) or update to IPython 2.x. It also causes a possibly scary to a new user pop-up box when opening the notebooks warning that notebook has been automatically converted to the new format.

The down side of doing this update is that people on older versions of IPython will no longer be able to read the notebooks. In addition, we will need to update our build automation and sphinx setup to use the newer version of IPython.

My ultimate goal is to make sure our docs are fully compatible with both python2 and python3, but I figure if I'm going over the full docs build I might as well update the IPython dependency as well.
