-"""Create a fake CancelHook used instead of a dependency, it cannot be used to cancel!

-Certain actions require a CancelHook to be supplied if called directly. The only method
-we use from the LabThings CancelHook is ``sleep()``. The CanceHook ``sleep()`` works
-exactly like ``time.sleep()`` except with raise an ``InvocationCancelledError`` if the
-server receives a cancellation request.
-
-This is just an object with a sleep method.
