12. Returns the natural log of the Binomial Coefficient, "n choose k", the number of k-element subsets that can be selected from an n-element set.
13. Given log(a) and log(b) calculate log(a + b) boils down to log( exp(log_a) + exp(log_b) ) but this might overflow, so we turn this into log([exp(log_a - log_c) + exp(log_b - log_c)]exp(log_c)) and we set log_c == max(log_a,log_b) and so it becomes: LARGE + log(1 + exp(SMALL - LARGE)) == LARGE + log(1 + SMALL) ~= large the whole idea being to avoid an overflow (exp(LARGE) == VERY LARGE == overflow)
