NAME
       PGARank - returns the rank of a string in a population.

DESCRIPTION
       This is a value between 1,...,N (the population size).  The most fit string has rank 1, the least fit string has rank N.

INPUT PARAMETERS
       ctx    - context variable
       p      - the index of the string whose rank is desired
       order  - an array containing a unique rank for each string
       n      - the size of the array order

OUTPUT PARAMETERS
       none

SYNOPSIS
       #include "pgapack.h"
       int  PGARank(ctx, p, order, n)
       PGAContext *ctx
       int p
       int *order
       int n

LOCATION
       fitness.c

EXAMPLE
       Example:
       Determine the rank of string p.

       PGAContext *ctx;
       int i, popsize, rank, *order;
       double *fitness;

       popsize = PGAGetPopsize(ctx);
       order   = (int *)   malloc(sizeof(int)	 * popsize);
       fitness = (double *)malloc(sizeof(double) * popsize);

       for(i=0;i<popsize; i++) {
       fitness[i] = PGAGetFitness(ctx, p, PGA_OLDPOP);
       order[i]   = i;
       }

       PGADblHeapSort(ctx, fitness, order, popsize);
       rank = PGARank(ctx, p, order, popsize)
