         * 99r25 Improvements in fixing discrepancies between covariates          * (Module): This version comes late after having tested
         missing in result line but in model.          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few

           original PRAXIS program written in Algol W (published with errors,
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          ommitting the transposition of matrix V before its QR reduction
           from Golub. I used the recent "awe" compiler from Gkynn Webster.
         * ./ (Module): Fixed bug on result:          The awe library had errors, for example in arc tangent function
           which have been fixed.
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>  
           The main objective was to get identical results with the three
         * imach.c (Module): Fix bug on quitting after result lines!          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         (Module): Version 0.99r21          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.

           Also, in order to compare them, the random function had to produce

           imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          'normal' mathematical arrays starting from 1 to n. But this is a
           real issue in C where, by default, arrays are starting from 0 to
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
           seen that authors while trying to mimick original Brent Algol W
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          code are hesitating by changing either a loop originally from 1 to
           n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          shifting the index from original X(I) in Algol W to x[i-1] in C.
         and life table from the data without any state)          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          the original Algol W arrays. Thus the X(I) is translated in C as
           x[i] which minimizes the errors. The Golub QR algorithm was
         * version.h: Summary: version 0.99.r19          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
         * imach.c: Summary: Projection syntax simplified          much more problematic in C than in Algol W.  Thus Buckhardt code
         We can now start projections, forward or backward, from the mean date          seems very safe, but i haven't chosen it for IMaCh because the C
         of inteviews up to or down to a number of years of projection:          style is horrible and almost unreadable compared to Gegenfürtner
         prevforecast=1 yearsfproj=15.3 mobil_average=0          CO code which is very close to Brent's original. Also what makes
         or          Buckhardt code more difficult to read is, instead of passing the
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          minimum of parameters in the functions calls, as it is in Algol
         or          Brent's code or Gegenfürtner's code, the list of parameters is
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          high. For example, the flin function LONG REAL PROCEDURE FLIN
         or          (LONG REAL VALUE L) has only one parameter in Algol W, the
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
         * imach.c: Summary: doxygen tex bug          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
