Togglable Legend, line on AreaRenderer
Pre-release

"What if I want to call callback() to get the callback back?"
Good evening,
New features! Togglable Legend:

Instantiate using new Plottable.ToggleLegend(). You can supply a callback that gets called when a legend item is clicked. Please see quicktests/legendToggle-quicktest.html for an example.
In addition, AreaRenderer can now draw a line above the shaded area:

Set the stroke by calling project("stroke", function() { return COLOR; })
IMPORTANT! The next release will feature a major re-arranging of the Plottable module space (almost certainly breaking all uses of the current API). You have been warned.
