Calculate the Cayley-Menger squared-distance matrix of an N-simplex from its points, and use the matrix’s determinant to compute the (interior) measure of the simplex—for example, the area of a triangle, or the volume of a tetrahedron.

This package exports two small utility functions, binomial2 and inverse_binomial2, as well as the full-featured immutable structured matrix type CayleyMengerDistanceMatrix and its constructors, and the function simplex_volume for calculating the measure directly from the points.
