Updated mapper classes descriptions
 r1397 Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Marek Rosa
Removed commented out code and unnecessary lines from model mapper classes
 r1379 The instance of this class cannot be created directly. QHPieModelMapper of QVPieModelMapper should be used instead. This class is used to create a connection between QPieSeries and QAbstractItemModel derived model object.
It is possible to use both QAbstractItemModel and QPieSeries model API. QPieModelMapper makes sure that Pie and the model are kept in sync.
NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells.
