 * .tsv (tab-separated values) format, with header row
inspections extraction:: add: script to pull inspections, given facility

e.g.,
$ cat ../data/facilities.tsv | ruby -Imechanize extract_inspections.rb
inspections extraction:: add: sample data file pulled using extract_inspections.rb

 * data updated as of 2013-10-01 2329
histories extraction:: add: utility for extracting inspection details

 * note: URL is not simply a GET request, you must pass REFERER, which
   can be 'http://eats.washoecounty.us/'
 * thx to elskwid figuring out that GET requests don't work without the
   REFERER set
