%INITDISTFIT Helper function to allow calls to m-file constructor

% This is the meat of the constructor.  It is here, rather than in distfit.m, 
% because there is no way to have another method, specifically copyfit, call
% the m-file constructor.  Since it is a method of the distfit object, it only
% calls the builtin.  An example of this workaround in action is in copyfit.
