Better cvp and voronoi algorithms
Add option to provide
voronoi vectors for
cvp() algorithm, much faster than basic
cvp. By setting
rtol it can be guaranteed that for positions on the boundary of Voronoi cells consistently the same closest vector is returned. The basic method was slightly changed, now it calculates the radius of the sphere in which every lattice point was generated and provably produces the
n shortest vectors.
reduced option to
voronoi() to remove superfluous vectors.
Closes #163 (closed).
