// .NAME vtkReebGraphToJoinSplitTreeFilter - converts a given Reeb graph
// either to a join tree or a split tree (respectively the connectivity of the
// sub- and sur- level sets).
// Note: if you want to use simplification filters, do so on the input Reeb
// graph first.
//
// Reference:
// "Computing contpour trees in all dimensions". H. Carr, J. Snoeyink, U. Axen.
// SODA 2000, pp. 918-926.
//
// .SECTION Description
// The filter takes as an input the underlying mesh (port 0, a vtkPolyData for
// 2D meshes or a vtkUnstructuredGrid for 3D meshes) with an attached scalar
// field (identified by FieldId, with setFieldId()) and an input Reeb graph
// computed on that mesh (port 1).
// The outputs is vtkReebGraph object describing either a join or split tree.
