Description
   Generate and process all the all the subsets of a list using the
   standard Perl metaphor.

   "subsets()" returns the number of subsets. Please note that this
   incloudes the empty set as it is a subset of all sets.

   Its easy to use and fast. Its written in 100% Pure Perl.

   Please note that the order in which the subsets are generated is not
   guaranteed, so please do not rely on it.

Export
   The "subsets()" function is exported.

Installation
   Standard Module::Build process for building and installing modules:

     perl Build.PL

     ./Build test
     ./Build install

   Or, if you're on a platform (like DOS or Windows) that doesn't require
   the "./" notation, you can do this:

     perl Build.PL
     Build
     Build test
     Build install
