// .NAME vtkPChacoReader - Read Chaco files
// .SECTION Description
// vtkPChacoReader is a unstructured grid source object that reads
// Chaco files. The file is read by process 0 and converted into
// a vtkUnstructuredGrid. The vtkDistributedDataFilter is invoked
// to divide the grid among the processes.
