Multi-threading
If you use Casbin in a multi-threading manner, you can use the synchronized wrapper of the Casbin enforcer: https://github.com/casbin/casbin/blob/master/enforcer_synced.go.
It also supports the AutoLoad feature, which means the Casbin enforcer will automatically load the latest policy rules from DB if it has changed. Call StartAutoLoadPolicy() to start automatically loading policy periodically and call StopAutoLoadPolicy() to stop it.
