Erlang B and C probabilities

Computes Erlang B and C probabilities

You are now following this Submission

This is a pair of routines for
computing Erlang B and C probabilities used in queueing
theory and telecommunications.
The routines use a numerically stable recurrence relation which works well for large numbers of servers. This revised version also includes a routine for computing Engset blocking probabilities.
