         * 99r25 Improvements in fixing discrepancies between covariates          The awe library had errors, for example in arc tangent function

           Gegenfürtner C versions on the various test functions published by
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          Brent in 1973 in Algol W.
   
         * ./ (Module): Fixed bug on result:          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
         * imach.c (Module): Fix bug on quitting after result lines!          'normal' mathematical arrays starting from 1 to n. But this is a
         (Module): Version 0.99r21          real issue in C where, by default, arrays are starting from 0 to
           n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
           shifting the index from original X(I) in Algol W to x[i-1] in C.
           But as IMaCh is using, since the beginning, the Numerical Recipes
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          functions vector or matrix, I changed Geggenfürtner code to mimick
           the original Algol W arrays. Thus the X(I) is translated in C as
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          seems very safe, but i haven't chosen it for IMaCh because the C
         and life table from the data without any state)          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * version.h: Summary: version 0.99.r19          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * imach.c: Summary: Projection syntax simplified          (LONG REAL VALUE L) has only one parameter in Algol W, the
         We can now start projections, forward or backward, from the mean date          Gegenfürtner flin function had two parameters: static double
         of inteviews up to or down to a number of years of projection:          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         prevforecast=1 yearsfproj=15.3 mobil_average=0          function has 14 parameters which makes the code unreadable and
         or          useless. Gegenfürtner used a lot of static variables or functions
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          which I tried to minimize. Also in Gegefürtner, array dimensions
         or          were fixed to N. In my adaptation the flin is static double
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          flin(double l, int j) and the parameter used are global variables.

         The number n which was limited to 20,000 cases is now unlimited, from firstobs to lastobs. If the number is too for the virtual memory, probably an error will occur.
