          readpopdens - Read population density data from file

     SYNOPSIS
          #include "lpj.h"

          Bool readpopdens(const Popdens popdens,
                           int year,
                           const Cell grid[],
                           const Config *config);

          popdens
               Pointer to population density data.  Must be
               initialized by initpopdens().

          year Sets year data is read.

          grid Cell grid array allocated and initialized by newgrid().

          config
               LPJmL configuration data. Must be read by readconfig().


     RETURN VALUE
          Upon successful completion FALSE is returned and TRUE on
