A priority queue must at least support the following operations: is_empty: check whether the queue has no elements. insert_with_priority: add an element to the queue with an associated priority. pull_highest_priority_element: remove the element from the queue that has the highest priority, and return it. This is also known as "pop_element(Off)", "get_maximum_element" or "get_front(most)_element".
