Port to C# [link in description]

[MWstudios]

I finished the port to C#. Let me know in issues if there is a bug or a typo on my side:
https://github.com/MWstudios/C-Sharp-DT
I still have slight doubts about if some things were ported correctly. IIRC std::unordered::map::operator[] creates a new key if it doesn't exist, so I replicated the behavior with Dictionary<T>(). detail::selection_sort() is replaceable with List.Sort() (though that does a quick/heap sort) and predicates::Epsilon<T>() should be equal to 2^-52 (again, my assumption).

It also occasionally crashes/asserts on thin triangles when minDistToConstraintEdge is set to low values (below 10), though I'm unsure if it's a bug on my part.

Hi, and thanks for the heads up @MWstudios.
I converted it into a discussion as it is a more fitting.

Okay then. I've also ported the Ruppert refinement branch, haven't actually tested it though.

The crashing problem seems to have disappeared after I found an oversight in my code (sorting edge vertices in constructor). The source of the issue wasn't obvious until after recently updating the port to the newest version.
