Scatterplot & BarChart: initial brushing mechanism.

* Both components now support brushing (support in Scatterplot for
  activating a brush is still incomplete, though it can be brushed
  on by other components)
* Added a handler for linking the brushing between components
* Added crosshair geometry handler to geometry lib
* Fixed issue #15
