// .NAME vtkCMBModelWriterBase - Writes out a CMB file on the server.
// .SECTION Description
// Writes out a CMB file on the server.  It currently gets written
// out as a vtkPolyData using vtkXMLPolyDataWriter with the necessary
// information included in the field data.  It writes out the current
// version unless specified otherwise.
