     Summary: Adding ftolpl parameter
     Author: N Brouard
   
     We had difficulties to get smoothed confidence intervals. It was due
     to the period prevalence which wasn't computed accurately. The inner
     parameter ftolpl is now an outer parameter of the .imach parameter
     file after estepm. If ftolpl is small 1.e-4 and estepm too,
     computation are long.

     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.

     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.
