% same = DescribeMonCal(cal,[file],[whichScreen])
%
% Print descriptive information about a calibration
% to the command window or file.
%
% Argument file is a standard Matlab file descriptor,
% see fopen. If file arg is omitted or empty, printout
% goes to command window.
%
% If argument whichScreen is passed, a description of
% the current hardware is also printed. In this case,
% returned boolean same indicates whether the calibration
% is consistent with the current hardware. Boolean
% same is empty if whichScreen is not provided.
%
% 8/25/97 dhb, pbe Wrote it.
% 7/3/98 dhb, pbe Updated for cal.describe.
% 12/3/99 dhb, mpr Fix check for calibration desription field.
% 8/1800 dhb Add whichScreen arg, same return.
% 6/29/02 dgp Use new version of Screen VideoCard.
% 9/23/02 dhb, jms Fix small bug in way driver is compared, presumably introduced 6/29/02.
% 9/29/08 dhb, tyl, ijk Update for OS/X, current computer stuff.
% Comparison of computer name skipped, because it seems to vary with login.
% 6/24/11 dhb Dump out gamma fit type and exponents if gamma function was fit with a simple power function.
% 5/28/13 dhb Change output printed format to make it easier to paste into Doku wiki.
