//  This code is an extension of the algorithm presented in the paper:
//  Parallel Peak Pruning for Scalable SMP Contour Tree Computation.
//  Hamish Carr, Gunther Weber, Christopher Sewell, and James Ahrens.
//  Proceedings of the IEEE Symposium on Large Data Analysis and Visualization
//  (LDAV), October 2016, Baltimore, Maryland.
//
//  The PPP2 algorithm and software were jointly developed by
//  Hamish Carr (University of Leeds), Gunther H. Weber (LBNL), and
//  Oliver Ruebel (LBNL)
//==============================================================================

// NOTE: To save test time, we reduced test coverage on September 2th 2024. The
// tests still running should be sufficient to uncovoer any issues due to VTK-m
// changes. However, if we continue development of the contour tree algorithm,
// we should re-enable the additional tests as they have revealed problems in
// the past.
