Overview

Schedule manages a JobQueue which contains Job instances, and a thread which pops and executes them. For simplicity’s sake, the Unicron module manages a default Schedule, but you can create and manage your own if necessary. Each uses its own JobQueue and thread, so they will not interfere with each other.
