Name: Exercise 6

Author: Steven Waters <stevenwaters@mail.usf.edu>

Date: 12-08-14

Features: The program will prompt the user to create records for 3 employees. Each record consist of the following values: 
		  - First Name 
		  - Last Name 
		  - Gender
		  - Social Security Number
		  - Payroll 
		  - Position
		  Furthemore, when these values are extracted from user input, they are passed to the Employee constructor as arguments. 
		  The Employee constructor then passes the first name, last name, gender, and the social security number to the Person consturctor 
		  which then passes the first and last name values to the Name constructor. Each of the classes for these constructors allows the 
		  worker object to print out these values by invoking the info() method. 

Bugs: None at the moment.
