Description
The vertex welding code converts a "soup of triangles", e.g. from an STL mesh, into a mesh whose triangles share vertices.
The code currently depends on std library functionality, e.g. hashmaps (`std::unordered_map`) and `std::hash`,
as well as `spin::RectangularLattice` (which is being ported in #677). GPU-ready hashmaps are the subject of #630
https://github.com/LLNL/axom/blob/18f7408e72e2924e71edde1938648cb0a9019c10/src/axom/quest/MeshTester.hpp#L367-L400
This might be helpful for improved robustness in the `SignedDistance` query. See, e.g. #703.

Research direction
Start with the vertex-welding implementation referenced in src/axom/quest/MeshTester.hpp at lines 367-400. Review the std::unordered_map, std::hash, and spin::RectangularLattice dependencies, along with related work in #677 and #630. Done means the vertex-welding path is portable to GPUs through RAJA and its impact on the SignedDistance query can be evaluated.
