add custom style for jqRangeSlider
move date-range-slider above the container to make it full-width-able
add month scales to the dateRangeSlider
don't specify the controller in $route.config if the view provides its own ng-controller
initialize the DateRangeService on routeChange to verify $location is updated
move model into model.data to avoid overwriting model.summary
proper value checking on setters, update $location as necessary, better min/max/defaults
change model.data and model.summary binding
