reusing scraping code from may exercise
parsing estate total
parsing units
wip: improving unit parsing retry logic
updated ruby version
switching back to poltergeist (with longer timeouts to avoid checkBlk errors)
also catching all exceptions resulting from checkBlk with infinite retries
added infinite retry if no block numbers parsed
added map views to asset paths
updated gemspec to allow Rails 4.1
added scraping code for 2014 May, works for estates
updated README and bumped version
Merge branch '2014May'
