// .NAME vtkCMBModelWriterV4 - Writes out a CMB version 4.0 file.
// .SECTION Description
// Writes out a CMB version 4.0 file.  It currently gets written
// out as a vtkPolyData using vtkXMLPolyDataWriter with the necessary
// information included in the field data.
// The format for storing the model entity Ids for each model entity group
// is not that straightforward since every model entity group could potentially
// be grouping a different amount of model entities.  The way that I chose to do it
// is to have a single index flat array that stores all of the needed information.
// The format of the data in the array is:
// number of model entities in first model entity group
// the Ids of the model entities in the first group
// number of model entities in second model entity group
// the Ids of the model entities in the second group
// ...
// number of model entities in last model entity group
// the Ids of the model entities in the last group
