Josh Baker 7538cc73ff avoid recover calls for non-lua queries 
The defer recover() pattern is expensive and only Lua queries require
it, so for now we'll just check if lua is being used before calling.

Alex Roitman b55300b729 Lua scripting feature. (#224) 
* Start on lua scripting

* Implement evalsha, script load, script exists, and script flush

* Make sure eval/evalsha never attempt to write AOF

* Add eval-set and eval-get to benchmarks

* Fix eval benchmark tests, add more

* Improve benchmarks

Josh Baker f9fa48db21 use redis-style expires 
Updated the Tile38 expires to match the Redis implmentation at
https://redis.io/commands/expire#how-redis-expires-keys.

It now supports passive and active expires with sub-millisecond
accuracy.

This addresses issue #156

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.
