new version of 3-body helium potential * precompute r^-i, * cos(n*theta), cosines of various theta sums, differences * switch some parameters from multidimensional arrays to simple scalars * rearrange permutations to make the nature of the permutations clearer * renumber distances & angles so that distance i is opposite angle i * initialize parameters in the constructor * add a method that takes the various r^2 values - implement IPotentialAtomicMultibody
