\class QPieSeries
\brief Pie series API for QtCommercial Charts
The pie series defines a pie chart which consists of pie slices which are QPieSlice objects.
The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices.
Jani Honkonen
Review corrections for pie
 r386 The actual slice size is determined by that relative value.

Refactor pie (again). QPieSlice's now emit signals and no id's anymore. Just pointers in the interface.
 r203 // update slice attributes
qreal sliceAngle = m_pieStartAngle;

Added a pie chart customization example and refactoring the pie interface.

Add animations to pie. Works but has some visual issues when adding slices.
