Detailed Description

This is the selection model used by spread sheet view.

It manages two operations:

• When the QItemSelectionModel is updated by the QAbstractItemView due to user interaction, pqSpreadSheetViewModel::select() gets called. In that overload, this class creates a 'ParaView Selection' i.e. create a selection source proxy for an ID based selection and set it as the selection-input (vtkSMSourceProxy::SetSelectionInput) on the data-source being shown in the view.
• Whenever the pqSpreadSheetViewModel receives new selection data from the data-server, it updates its internal QItemSelection and fires pqSpreadSheetViewModel::selectionChanged signal. pqSpreadSheetViewSelectionModel handles that signal by updating itself to mark the corresponding elements as selected.
