  1. Re-written as a rake task; save as "Rakefile" and run as "rake db:seed feed=FEED_ID".
  2. entry ID alone not sufficient as unique key (may appear in several feeds); so prepended feed sup_id.

Changed step back to 9900; don't think anything above this returns more results.

Added a sleep() to this version of code.
