[ABE.pm] trapping warnings

[Faber J. Fedor]

I've got some code like this:

  $sum = $indexTable2->elm($i, "weight");
  while ($sum <= $captPercentile) {
      $sum += $indexTable2->elm($i+1, "weight");
      $bottom_count ++;
      $i++;
  }

If indexTable2 is empty (it should never be, but hey this is RL), I get
errors like:

Row index out of range [0..-1]Use of uninitialized value in addition (+) at /home/sqa/bin/processMonthlyData.pl line 497.

And the program will sit in that loop forever, spitting out this
warning/error to STDOUT.

How do I trap this and DIE with an error message?
