Problem Set

1. Using the CPAN web site, locate a module for verifying credit card numbers. Download and build it (don't try to install it, because you need root privileges to do this).
2. If you have already solved the codons problem, create a module that contains the single function translate. This function will take a DNA string and translate it into a protein string using the 1-letter amino acid code.

   If you haven't solved the codons problem yet, come back to this one when you have time.
