A perl module to parse a domain down to the root TLD utilizing the
Mozilla Public Suffix List.

This module utilizes the "public_suffix_list.dat" or "effective_tld_names.dat"
provided by Mozilla as a way to effectively reduce a fully qualified
domain name down to the absolute root. The Mozilla PublicSuffix file
is an open source, fully documented format that shows absolute root
TLDs, primarily for Mozilla's browser products to be able to determine
how far a cookie's security boundaries go.
