// .NAME vtkQtInitialization - Initializes a Qt application.
//
// .SECTION Description
// Utility class that initializes Qt by creating an instance of
// QApplication in its ctor, if one doesn't already exist.
// This is mainly of use in ParaView with filters that use Qt in
// their implementation - create an instance of vtkQtInitialization
// prior to instantiating any filters that require Qt.
