Speedup varies between 5-15% depending on doc
Reworked bson.cc to throw error when trying to serialize js bson types
Added MinKey, MaxKey and Double support for JS and C++ parser
Reworked socket handling code to emit errors on unparsable messages
Added logger option for Db class, lets you pass in a function in the shape { log : function(message, object) {}, error : function(errorMessage, errorObject) {}, debug : function(debugMessage, object) {}, }
Usage is new Db(new Server(..), {logger: loggerInstance})
