CPTPieChart startingAngle normalization

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set up a pie chart with a starting angle of > 2*pi and some slices.
2. Add a delegate to handle sliceWasSelectedAtRecordIndex.

What is the expected output? What do you see instead?
When you click on a slice now the returned index is wrong.

What version of the product are you using? On what operating system?
CorePlot trunk, OSX 10.7.2, XCode 3.2.6

Please provide any additional information below.
The current code doesn't work well with angles outside the 0..2*pi range. So in 
order to counter that and also as a matter of defensive programming CPTPieChart 
should normalize the given starting angle to the expected range. The attached 
patch does exactly this.

Well, I think the problem can only be repeated with angles < 0 or better < 
-2*pi. I had angles like -111 due to user interaction.
