    \class QHBarModelMapper
    \brief part of QtCommercial chart API.
    \mainclass

    Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
    Horizontal model mapper is used to create a connection between QBarSeries and QAbstractItemModel derived model object.
    Model mapper maintains equal size of all the BarSets.
    Adding/removing value from the BarSet causes the the same change in the rest of the BarSets added to the same series.
    NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells.
