                 \mainclass
                 The instance of this class cannot be created directly. QHBarModelMapper of QVBarModelMapper should be used instead. This class is used to create a connection between QBarSeries and QAbstractItemModel derived model object.
                 Curently it is NOT possible to use both QAbstractItemModel and QBarSeries model API.
                 When the series is set to the mapper the QBarSeries and QBarSet API that affect the data (append, setValue, remove) should not be used.
                 The model and the QBarSeries won't be kept in sync. Model API should be used to insert,remove,modify BarSets.
                 NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells.
