function jcb_rpt( p, t, s, d, ttle )
%JCB_RPT - Reports graphically the results of a pumping test interpreted with the Cooper-Jacob (1946) model. 
%                        
% Syntax: jcb_rpt( p, t, s, d, ttle )
%
%   p = parameters of the model
%   p(1) = a  = slope of the straight line
%   p(2) = t0 = intercept with the horizontal axis for s = 0
%   t = measured time
%   s = measured drawdown
%   d(1) = q = Pumping rate
%   d(2) = r = distance from the pumping well 
%   ttle = Title of the figure 
%
% Description:
%   Produces the report of an intepretation made with the Cooper and Jacob
%   (1946) solution.
