Updated BarModelMapper docs
 r1485 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.

VBarModelMapper allows you to use your own QAbstractItemModel derived model with data in columns as a data source

 r1516 for any bar series. It is possible to use both QAbstractItemModel and bar series data API to manipulate data.
VBarModelMapper keeps the series and the model in sync.
The following QML example would create a bar series with three bar sets (assuming the
