Josh Baker 04290ec535 KNN results for NEARBY command
This commit includes the ability to search for k nearest neighbors using
a NEARBY command. When the LIMIT keyword is included and the 'meters'
param is excluded, the knn algorithm will be used instead of the
standard overlap+haversine algorithm.

   NEARBY fleet LIMIT 10 POINT 33.5 -115.8

This will find the 10 closest points to 33.5,-115.8.

closes #136, #130, and #138.
