Start of summary visualization
Calculates only for selected group. Still need to make sure its only one group at a time.
Merge remote-tracking branch 'jim/summary_vis' into jpSummaryVis
Summary vis now has error checking for null.

The baseVis now supports y axis fields - including radio buttons.

Histogram now overrides baseVis instead of taking advantage of bad design in baseHighVis.

BaseHighVis has been reduced by giving functionality to baseVis for YAxis tools.

BaseVis now provides support for grouping by radio button.

Summary vis is complete.
Table now has hidable rows and the groupByField is colored according to the grouping type
Fixed a bug with running out of colors
