The input to the constructor is String Name, String SSNumber, int EmpID, 
String Dept, int YearHired, double TotalYearlyWages

The '#' means it is protected.  The name and SSNumber are the name and Social
Security number of the person.  The Calender (which is in the package of
java.util.*, is needed to calculate the years of service.  I.e., it is
used to get the current year.  A person is allowed to change their name, e.g.,
by marriage.  Each employee has a EmpID, a dept they belong to, and a year in
which they were hired.

	The default constructor is to assign a special value to name to indicate
that no name was given, e.g. "No Name was Given".  Each of the constructors will
have the line:


	calender = new GregorianCalendar();


which creates the calender.  The other methods are obvious.  Note that
toString will output on one line the person's name and Social Security
number, with a label for each one.  On another line it will output the EmpID,
dept, and yearHired.  It will NOT ouput the TotalYearlyWages.  The toString
will just give general information.
