/**
 * HelpDeskRunner v1.0
 * @author Dennis Brylow
 * Runner class parses input and provides output for the
 *  Project 3 HelpDesk simulator.  This Runner assumes your
 *  HelpDesk class provides the following API:
 * 
 *  public void step()
 *    Advance the simulation one minute.
 * 
 *  public void addStudent(String name, int course, int workload)
 *    Add an arriving student with the indicate name, course number, 
 *    and minutes of workload. If the current student has a lower or
 *    equal course number, the arriving student is turned away.
 *    If the current student has a higher course number, the current
 *    student is preempted while the new student is helped.
 * 
 *  public int getTime()
 *    Get the current simulation time in minutes.
 * 
 *  public String toString()
 *    Return the status of the simulation. This produces strings like, 
 *    "Time 2, Helping Jack from COSC1010", or "Time 9, IDLE".
 * 
 *  public String getLog()
 *    Return the entire HelpDesk session log.
