Bokeh charts

OK, this is the Bokeh chart interface, at least the very beginning... there is a lot of thing to add... a lot of thins to refactor... 
Currently it is supporting histograms, bar, scatter charts. Grouped and stacked. Support OrderedDict and pandas object as inputs. And we support kwargs and chained methods.
Yeah, I agree... with "some time", I think you are meaning after the release, don't you? Or you want to make it now?
