/**
* @class vtkDIMACSGraphReader
* @brief reads vtkGraph data from a DIMACS
* formatted file
*
*
* vtkDIMACSGraphReader is a source object that reads vtkGraph data files
* from a DIMACS format.
*
* The reader has special handlers for max-flow and graph coloring problems,
* which are specified in the problem line as 'max' and 'edge' respectively.
* Other graphs are treated as generic DIMACS files.
*
* DIMACS formatted files consist of lines in which the first character in
* in column 0 specifies the type of the line.
*
* Generic DIMACS files have the following line types:
* - problem statement line : p graph num_verts num_edges
* - node line (optional) : n node_id node_weight
* - edge line : a src_id trg_id edge_weight
* - alternate edge format : e src_id trg_id edge_weight
* - comment lines : c I am a comment line
* ** note, there should be one and only one problem statement line per file.
*
*
* DIMACS graphs are undirected and nodes are numbered 1..n
*
* See webpage for additional formatting details.
