Bokeh

- integrated bokeh on backend&frontend side (bbossy's changes)
- added example workbook
- started work on "simplification" layer for bokeh-scala (imho poorly documented, please give feedback here -> software design could probably be better... not 100% sure yet on which direction to take). Idea: simplify the 80% tasks/plots data analyst have to do in terms of plots/statistical analysis.
- added spark configurator workbook
At Austin, Tx for the final of a data analytics contest (texata). I actually agree on the bokeh-scala part.  Cheers
