Detailed Description
DatasetProxyModel takes a KChart dataset configuration and translates it into a filtering proxy model.
The resulting model will only contain the part of the model that is selected by the dataset, and the according row and column header data.
Currently, this model is implemented for table models only. The way it would work with models representing a tree is to be decided.
The column selection is configured by passing a dataset description vector to the model. This vector (of integers) is supposed to have one value for each column of the original model. If the value at position x is -1, column x of the original model is not included in the dataset. If it is between 0 and (columnCount() -1), it is the column the source column is mapped to in the resulting model. Any other value is an error.
