/**
* @class vtkPerturbCoincidentVertices
* @brief Perturbs vertices that are coincident.
*
*
* This filter perturbs vertices in a graph that have coincident coordinates.
* In particular this happens all the time with graphs that are georeferenced,
* so we need a nice scheme to perturb the vertices so that when the user
* zooms in the vertices can be distiquished.
