// .NAME vtkPVVectorEntry - ParaView entry widget.
// .SECTION Description
// This widget allows user to enter text. It has a label and can have
// multiple fields. The maximum number of fields is 6. Once the widget
// is created the number of fields cannot be changed. When the user
// modifies the entry, the modified callback is called.
