-%%% This is a rewrite of overload from BS.3, by Peter Högfeldt.
-%%%
-%%% DESCRIPTION
-%%%
-%%% This module implements a server process that keeps record of the
-%%% intensity of calls of the request/0 function, and answers accept or
-%%% reject depending on if the current average intensity is not greater 
-%%% than a specified maximum intensity.
-%%%
-%%% The intensity i is calculated according to the formula:
-%%%    i(n) = exp(-K*(T(n) - T(n-1)))*i(n-1) + Kappa
-%%% where i(n) is the intensity at event n, Kappa is a constant, and
-%%% T(n) is the time at event n.
-%%%
-%%% The constant Kappa can be thought of as 1 / T, where T is the time 
-%%% constant. Kappa is externally referred to as Weight.
-%%%  
-%%% We keep track of two intensities: the total call intensity and the 
-%%% intensity of accepted calls.
-%%%-----------------------------------------------------------------
-%%% TODO
-%%%
-%%% 3. Hysteresis.
