Description
Expect latlngs in column_A to match with geohashes in column_B.
The more digits a geohash has, the smaller and more precise of an area it represents. When converting a latlng to a geohash, we are only asserting that it falls somewhere within the other geohash we're comparing it with. To verify this, we only need to make sure that they share their left-most digits. For example, dpz8 contains dpz80 (in addition to any other geohash that begins with "dpz8".
