Retriangulating perturbed data sets

[DanielVandH]

Would be especially nice for cell simulation problems to have a repair! function for retriangulation of near-Delaunay triangulations, as implemented in https://dl.acm.org/doi/10.1145/1064092.1064129 or https://doi.org/10.1111/j.1467-8659.2010.01812.x
