Begin Replication
function light.begin_replication()
Can be called at any time to allow messages to be sent on the client or
server, but it's best to get it out of the way. Calling multiple times or from multiple files has no additional effects.
If you call it later on, all of the messages you try to send will still get queued up.
function light.begin_replication
You can use light.step_replication()
instead of this if you prefer a manual
replication step.
