Excel-like data grid editor for Pandas in the IPython notebook with Handsontable

This proof-of-concept brings an interactive Excel-like data grid editor in the IPython notebook, compatible with Pandas' DataFrame. It means that whenever you have a DataFrame in the IPython notebook, you can edit it within an integrated GUI in the notebook, and the corresponding Python object will be automatically updated in real-time.

This proof-of-concept uses the new widget machinery of IPython 2.0. You need the latest development version of IPython (or v2.0beta, or v2.0 when it's released within the next few weeks). You also need the Handsontable Javascript library. Other data grid editors could probably be used as well.
