add /regions/ which dumps geohashes
pull out GeoHashRegion from LatLon
expose simplistic bounding box
fixed bug in GeoHashRegion#boundingBox, was not actually getting top left x value correct because I was thinking in terms of screen x, y, and not cartesian x + changed around formatting a little
add simple links to dumps of ngrams
added logging to Graphite of counts many regions; I may remove in a sec because local client is a bit flaky
only log overall total
playing with surprisingness i.e. the ratio between expected number of occurrences based on overall occurences, and the actual number of occurrences
added impl of ordering ngrams by TFIDF score, where document = geohash region, term = ngram, and frequency = tweets for ngram in region
added some embedded urls
