// .NAME vtkModelGeneratedGridRepresentation - Abstract class for a generated
//  CMBModel representation of an analysis grid.
// .SECTION Description
// An abstract class used to provide all of the information that a CMBModel needs
// to keep track of mapping grid objects from the geometry grid to the
// analysis grid. In this case the analysis grid isn't read in from a file
// but instead is generated by some code.
