Code needs to be done in C++. - Consider customer service of an emergency room (ER) in a hospital. A patient in ER is placed in a waiting list based on how much its situation is urgent compare to other patients. For example, if a case is very urgent, it should be serviced before other patients who are less urgent, even they have been in the waiting list long before. Also, if two patients have the same urgency, normally the one who comes earlier will be serviced first.

1. Develop a class for ER waiting list named ERWL (ER.h) using generic types with necessary member functions including constructor(s), destructor(s), insert (adds a new patient into the list given his/her status) and remove (removes the patient from the list with the most urgent status).
