Updated mapper classes descriptions
 r1397 Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Marek Rosa
Model mappers docs updated
 r1378 Horizontal model mapper is used to create a connection between QPieSeries and QAbstractItemModel derived model object that keeps the consecutive pie slices data in rows.
Marek Rosa
Added documentation for PieModelMapper classes
 r1340 It is possible to use both QAbstractItemModel and QPieSeries model API. QHPieModelMapper 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.

\qmlclass HPieModelMapper QHPieModelMapper
HPieModelMapper allows you to use your own QAbstractItemModel derived model with data in rows as a data source
for a pie series. It is possible to use both QAbstractItemModel and PieSeries data API to manipulate data.
HPieModelMapper keeps the Pie and the model in sync.
The following QML example would create a pie series with four slices (assuming the model has
at least five columns). Each slice would contain a label from row 1 and a value from row 2.
\code
HPieModelMapper {
series: pieSeries
model: customModel
labelsRow: 1
valuesRow: 2
firstColumn: 1
columnCount: 4
}
\endcode
