%  This subroutine accomplishes reweighting of posterior simulator output
%  and/or construction of new functions of interest.  The code given here
%  leaves the prior and functions of interest unchanged, and therefore
%  accomplishes nothing.  This code must be replaced by code specific to
%  the client's interests.
%  Inputs:
%  npar    Number of functions of interest in the investigator's posterior
%          simulation file.
%  thetai  Vector of dimension npar, containing the parameter values read from
%          the investigator's simulation file in the current record.
%  pri     Logarithm of the investigator's prior evaluated at thetai
%  Outputs:
%  nc      Number of functions of interest in the client's posterior simulation
%          file.
%  gc      Vector of dimension nc, containing the values of the client's
%          function of interest
%  priorc  Logarithm of the client's prior evaluated at thetai

function [nc, gc, priorc]=client(npar,thetai,pri);
   nc=npar;
   priorc=pri;
   gc=thetai(1:nc);
