- brute force tester to make sure queen and rook are correct
- for the national case the queen here matches queen from opengeoda
  (histograms)
- rook are slightly different between the two (here v. opengeoda)
- rook for columbus agrees for bf and open geoda
- but rook for nation does not
Merge branch 'master' of github.com:pysal/pPysal
- now rook matches opengeoda
- it is slower than queen but both histograms match opengeoda for national
  counties shapefile
- fixed logic bug in rook checker. now much faster and matches opengeoda with
  regard to connectivity histogram
- timings against current pysal
- faster!
- case sensitive file systems
