Fix to avoid inefficient compution of chart properties upon focussing on a specific x-axis range
Pie charts can now be configured to display top N and the rest as one 'Others' slice
Added zoom and drag support to coordinate grid charts. Listeners on these events can be installed. An anpi to specify the range-selection-chart, if any, of a main chart is provided so that the zoom and drag actions can updated the slider/brush on the range selection chart as well.
rangeSelChart now adjusted correctly w.r.t to the filter derived from zoom/drag actions
