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.
