Support sunburst graphs #37

Moved from Google Code issue #563.

Add support for sunburst graphs. This type is very similar to pie/dognut charts but with stacking and incomplete rings.

You can make that example plot with the existing pie chart, although it would require a separate plot for each ring and some work in the datasource to figure out where the blank pie slices should go.
