 * A transition is defined as an action that ends a current queue entry and immediately starts a new one
 * with (slightly) different values. For now, this could be used to transition the queue entry's status,
 * priority or queue. This allows us to keep a history of queue entries through a patient's visit.
 * Note that there are some use cases (like RDE or data correction) where a transition is NOT appropriate.
