Detailed Description

Template Action used in ex04_waypoints.cpp example.

Its purpose is to do make it easy to create while loops wich consume the elements of a queue.

Note that modifying the queue is not thread safe, therefore the action that creates the queue or push elements into it, must be Synchronous.

When ticked, we pop_front from the "queue" and insert that value in "popped_item". Return FAILURE if the queue is empty, SUCCESS otherwise.
