Title: Add a formatter function for value

Ben,
Thanks for your work on this library!
My pie chart has values which are actually dollars. I want to show the values as inner labels, and I need to include the dollar sign on the values - so I added in an optional function which the user can supply to format values before they're rendered.
Cheers,
Darren.
