Implemented the new assigning method using a Patient's "illTime" as
opposed to a room's "occupiedTime".

This can be changed using a boolean variable in the hospital class
called "assigningType" where type false/0 accesses the roomQueue, and
true/1 accesses the patientQueue.

THIS NEEDS THOROUGH TESTING, INCLUDING A NEW CONFIG FILE WITH PATIENTS
WITH VARIOUS ILLTIMES, AND A SINGLE DOCTOR, AND WATCHING WHO GETS
TREATED FIRST.
