/**
* @class vtkChacoGraphReader
* @brief Reads chaco graph files.
*
*
* vtkChacoGraphReader reads in files in the Chaco format into a vtkGraph.
* An example is the following
* <code>
* 10 13
* 2 6 10
* 1 3
* 2 4 8
* 3 5
* 4 6 10
* 1 5 7
* 6 8
* 3 7 9
* 8 10
* 1 5 9
* </code>
* The first line specifies the number of vertices and edges
* in the graph. Each additional line contains the vertices adjacent
* to a particular vertex. In this example, vertex 1 is adjacent to
* 2, 6 and 10, vertex 2 is adjacent to 1 and 3, etc. Since Chaco ids
* start at 1 and VTK ids start at 0, the vertex ids in the vtkGraph
* will be 1 less than the Chaco ids.
