SYNOPSIS
      use Data::TableAutoSum;
  
      my $table = Data::TableAutoSum->new(rows => 10, cols => 20);
      # or
      my $table = Data::TableAutoSum->new(rows => ['New York', 'L.A.', 'Chicago'],
      foreach my $row ($table->rows()) {
         foreach my $col ($table->cols()) {
            $table->data($row,$col) = rand();
            $table->data($row,$col) += $table->data($row-1,$col-1) 
                if $row >= 1 && $col >= 1;
         }
      }

      $table->change(sub {$_ = int ($_ / 10)}); # World War III perhaps
  
      print "Row $_ has result: ",$table->rowresult($_) for $table->rows();
      print "Col $_ has result: ",$table->colresult($_) for $table->cols();
      print "Table has the total result: ",$table->totalresult();   

      print "Let's have a look to the whole table:\n", $table->as_string;

      $table->store('random.dat');
      my $old_random_data = Data::TableAutoSum->read('random.dat');
      
      # or thinking, we have generated a 
      # table for the population( [cities], [centre, suburb] )
      # and a similar table with the crimes( [cities], [centre, suburb] )
      # we can calculate the crimes per citizen with
      $crime_rate = Data::TableAutoSum->merge(
         sub {shift() / shift()}, $crimes, $population
      );
