 /**
 @short A model to combine several QStandardItemModel's into one.
 Combine standard models into the aggregate model to display them in the one view.
 
 Each new model gets its own parent item to differentiate items between different models,
 for example:
 
 Tea Model:
 @code
 - Black
 - Green
 - White
 @endcode
 Coffee Model:
 @code
 - Arabica
 - Robusta
 @endcode
 
 When aggregated with
 @code
     AggregateModel model;
     model->addModel("Tea", teaModel);
     model->addModel("Coffee", coffeeModel);
 @endcode
 they will look as:
 @code
 - Tea
     - Black
     - Green
     - White
 - Coffee
     - Arabica
     - Robusta
 @endcode
 
 @note It is impossible to aggregate any model, aggregation works only for standard models.
 @note Currently aggregate model displays only 1 column.
