Add table-level database locking to ActiveRecord

Typically SQL is not a great place to store a counter that is incremented often. For instance if you're counting the number of visits to a page by incrementing a SQL column and that page gets popular then there's a good chance that the SQL counter will become a benchmark. This is because doing an UPDATE on the row in question locks the row during the course of the UPDATE. So for many concurrent UPDATES there will be lots of lock contention. This gem helps with that.

Mysql replication, could cause a number of issues if the tables that are being replicated are locked. Myreplicator is designed to replace Mysql's replication with a flat file based system. Myreplicator allows you to sync tables based on different frequencies and avoid using Mysql's built-in replication services.
