* @class vtkDIMACSGraphWriter
* @brief write vtkGraph data to a DIMACS
* formatted file
*
*
* 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 \em num_verts \em num_edges
*
* Followed by |E| edge descriptor lines that are formatted as:
*
* e \em source \em target \em weight
*
* Vertices are numbered from 1..n in DIMACS formatted files.
*
* See webpage for format details.
