`Comparator<Priority>`	`getPriorityComparator()`	Returns a `Comparator` that will be used to control priority order and thus effect the order in which work is attempted.
`void`	`promotePriority(Priority priority)`	Decides if the given instance of `Priority` should be adjusted and makes the adjustment if it should. Note: `CommManager` will call this method each time it is deciding if work should begin, implement accordingly.
