multiple focus charts for a range chart

[gordonwoodhull]

The question was asked on Stack Overflow how to have multiple focus charts for a single range chart:

http://stackoverflow.com/questions/27445259/dc-js-applying-range-chart-to-multiple-graphs

I created an example that monkey-patches a focusCharts method onto a coordinate grid chart, but it only handles the filter -> zoom direction.

A real solution would need to handle the focus-zoom -> range -filter direction, and that means thinking about the way focus chart is tied to range chart, and I hate thinking. ;-)
