     Revision 1.195  2015/08/18 16:28:39  brouard
     Summary: Adding a hack for testing purpose
   
     After reading the title, ftol and model lines, if the comment line has
     a q, starting with #q, the answer at the end of the run is quit. It
     permits to run test files in batch with ctest. The former workaround was
     $ echo q | imach foo.imach

     Some codes had been disabled in order to simplify and Vn*age was
     working in the optimization phase, ie, giving correct MLE parameters,
     but, as usual, outputs were not correct and program core dumped.

     We use directest instead of original Powell test; probably no
     incidence on the results, but better justifications;
     We fixed Numerical Recipes mnbrak routine which was wrong and gave
     wrong results.

     Summary: Debugging with valgrind
     Author: Nicolas Brouard
   
     Lot of changes in order to output the results with some covariates
     After the Edimburgh REVES conference 2014, it seems mandatory to
     improve the code.
     No more memory valgrind error but a lot has to be done in order to
     continue the work of splitting the code into subroutines.
     Also, decodemodel has been improved. Tricode is still not
     optimal. nbcode should be improved. Documentation has been added in
     the source code.
   
     Revision 1.143  2014/01/26 09:45:38  brouard

     (Module): Yes the sum of survivors was wrong since
     imach-114 because nhstepm was no more computed in the age
     loop. Now we define nhstepma in the age loop.
     (Module): In order to speed up (in case of numerous covariates) we
     compute health expectancies (without variances) in a first step
     and then all the health expectancies with variances or standard
     deviation (needs data from the Hessian matrices) which slows the
     computation.
     In the future we should be able to stop the program is only health
     expectancies and graph are needed without standard deviations.
