Updates to display totals linked to filtering events.
Updated dynamic top N clinic functionality within charts.  Updated tooltip on composite chart to show referral count breakdown by patient status.  Changed time scrubber to bar chart and shrunk it a bit.
Added colors and colorAccessors to link colors between clinic pie chart and composite clinic chart.
Able to remove color accessor because keys auto link to color scale (set up initially by using facility name as domain).
Moving the filter reset logic into the javascript file
Making page load function flow a lil bit clearer
