[IPython-dev] Resetting widget application view/state

Following the helpful discussion on widgets last month, we've made good
progress with our spectroscopy widgets and are very happy!

One issue we're having is that we want the user to be able to change which
datateset he/she is piping is working with.  Different datasets have
different default values, for example spectral units, start and end ranges

Right now, our application's view and model are completely separate;
however, when the user chooses to work with a new dataset, we'd like the
view to reset itself based on the new ranges for some of these attributes.
We were hoping there was a smart way to do this!  Even if it's a total
hack, that's fine.

Here is the notebook:


I've attached a ss of the ouput

The _filename_changed trait is where this new functionality should go.
