Detailed Description

Encapsulates selection data without exposing VTK types.

This class provides a VTK-independent interface for selection data, hiding the underlying vtkIdTypeArray implementation.

Following ParaView's design pattern, this class can now store information about multiple selected actors/representations along with their selection data.
