// .NAME vtkDIMACSGraphWriter - write vtkGraph data to a DIMACS
// formatted file
// .SECTION Description
// vtkDIMACSGraphWriter is a sink object that writes
// vtkGraph data files into a generic DIMACS (.gr) format.
//
// Output files contain a problem statement line:
//
// p graph <num_verts> <num_edges>
//
// Followed by |E| edge descriptor lines that are formatted as:
//
// e <source> <target> <weight>
//
// Vertices are numbered from 1..n in DIMACS formatted files.
//
// See webpage for format details.
