\class QVXYModelMapper

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 Vertical model mapper is used to create a connection between QXYSeries and QAbstractItemModel derived model object.
It is possible to use both QAbstractItemModel and QXYSeries model API. QXYModelMapper makes sure that QXYSeries and the model are kept in sync.
NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells.

VXYModelMapper allows you to use your own QAbstractItemModel derived model with data in columns as a data source
for XYSeries based series. It is possible to use both QAbstractItemModel and XYSeries data API to manipulate data.
VYModelMapper keeps the series and the model in sync.
