PARAMETERS FOR THE PROGRAM STRAT.  The program will also read details about
the input data file from the file "mainparams".  


"(int)" means that this takes an integer value.
"(d)"   means that this is a double (ie, a Real number such as 3.14).
"(B)"   means that this variable is Boolean 
        (ie insert 1 for True, and 0 for False).


#define NUMSIMSTATS  1000  // (int) number of simulated test stats per locus
#define NUMPHENS       2   // (int) number of phenotypes.  The phenotypes should
                                    be coded {0,1,...,NUMPHENS-1} 
#define POOLFREQ      10   // (int) pool alleles that have fewer than this many copies
#define LOCUSxONLY     0   // (int) Estimate a p-value for this locus only.  The loci 
                                    are numbered {1...L} according to their order in the
                                    input file.  Setting this to 0 turns this option off
                                    -- ie, p-values are estimated for all loci.
#define EMERROR     0.001  // (double) stop EM when change is less than this (>0)
