+   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.

    hPijx.
    Also this programme outputs the covariance matrix of the parameters but also
    of the life expectancies. It also computes the period (stable) prevalence.
+ Back prevalence and projections:
+  - back_prevalence_limit(double *p, double **bprlim, double ageminpar, double agemaxpar, double ftolpl, int *ncvyearp, double dateprev1,double dateprev2, int firstpass, int lastpass, int mobilavproj)
+     Computes the back prevalence limit  for any combination     of covariate values k
+     at any age between ageminpar and agemaxpar and returns it in **bprlim. In the loops,
+    - **bprevalim(**bprlim, ***mobaverage, nlstate, *p, age, **oldm, **savm, **dnewm, **doldm, **dsavm, ftolpl, ncvyearp, k);
+  - hBijx Back Probability to be in state i at age x-h being in j at x
+    Computes for any combination of covariates k and any age between bage and fage
+    p3mat=ma3x(1,nlstate+ndeath,1, nlstate+ndeath, 0,nhstepm);
+                         oldm=oldms;savm=savms;
+          - hbxij(p3mat,nhstepm,agedeb,hstepm,p,nlstate,stepm,oldm,savm, k);
+      Computes the transition matrix starting at age 'age' over
+      'nhstepm*hstepm*stepm' months (i.e. until
+      age (in years)  age+nhstepm*hstepm*stepm/12) by multiplying
+      nhstepm*hstepm matrices. Returns p3mat[i][j][h] after calling
+      p3mat[i][j][h]=matprod2(newm, bmij(pmmij,cov,ncovmodel,x,nlstate,prevacurrent, dnewm, doldm, dsavm,ij),\
+,nlstate+ndeath,1,nlstate+ndeath,1,nlstate+ndeath, oldm);
+ Important routines
+ - func (or funcone), computes logit (pij) distinguishing
+   o fixed variables (single or product dummies or quantitative);
+   o varying variables by:
+    (1) wave (single, product dummies, quantitative),
+    (2) by age (can be month) age (done), age*age (done), age*Vn where Vn can be:
+        % fixed dummy (treated) or quantitative (not done because time-consuming);
+        % varying dummy (not done) or quantitative (not done);
+ - Tricode which tests the modality of dummy variables (in order to warn with wrong or empty modalities)
+   and returns the number of efficient covariates cptcoveff and modalities nbcode[Tvar[k]][1]= 0 and nbcode[Tvar[k]][2]= 1 usually.
+ - printinghtml which outputs results like life expectancy in and from a state for a combination of modalities of dummy variables
+   o There are 2*cptcoveff combinations of (0,1) for cptcoveff variables. Outputting only combinations with people, éliminating 1 1 if
+     race White (0 0), Black vs White (1 0), Hispanic (0 1) and 1 1 being meaningless.
