/**
* @class vtkReebGraphSimplificationMetric
* @brief abstract class for custom Reeb graph
* simplification metric design.
*
* This class makes it possible to design customized simplification metric
* evaluation algorithms, enabling the user to control the definition of what
* should be considered as noise or signal in the topological filtering process.
