Flesh out PandasDataSource about bokeh

[bryevdv]

@pzwang This is purely on the python side as a convenience? (i.e. could they actually be realized as standard ColumnDataSource on the js side?) That should be fairly simple then..

@mattpap are we still using this for CDX?

[mattpap]

We don't. I was going to review this kind of code during another round of work on widgets.

so then I think we should just remove it. There is probably a better way to do this sort of thing now. You can pass dataframes into ColumnDataSources just fine ColumnDataSource(data=df) so essentialy our column data source is a pandas source. That old pandas source used to do some fancy stuff that we should probably do with server side data or something

I am inclined to agree. Propose: mark this invalid and close, open new ticket to remove PandasDataSource (and also PandasPlotSource on the js side?)

I agree...
