=head2 FUNCTIONS FOR WAIT PROBABILITY

=over

=item B<$wprob = wait_probability($traffic, $servers);>

Evaluate the probability that a call will have to wait in the queue
because all servers are busy.



=item B<$servers = servers_waitprob($traffic, $wait_probability)>

Evaluate the needed number of servers to handle $traffic Erlangs with
a wait probability not greater than $wait_probability.
