Added Gantt class with constructor, getQueue, and display and metrics functions.
Created a Gantt class, and the start of a PCB class. INcluded a display function that iterates over a given vector and prints out the PIDs, seperated by a '|'. It is assumed that the given vector is the resultant vector of an aglo being run.
