CPTR-142 Homework #5 - Due Wednesday  4/16/14
    
    Write a program in which a class called Odometer is defined.
    This class will be used to track fuel and mileage for a vehicle.
    Include private member variables to track miles driven and
    gallons of fuel used.  The class should have a default constructor
    that initializes miles and gallons to zero.  There should be
    member functions to reset the odometer and gallons to zero,
    a member function that accepts miles driven for a trip and adds
    it to the odometer's total, a member function that accepts gallons
    used and adds it to the total gallons, and a member function
    that returns the miles-per-gallon since the odometer was last
    reset.  This will be called program 5.
    
 
    Write a main that will declare two or more odometer objects
    (presumably representing two or more vehicles),
    puts data into them, calls to get the mileage (miles-per-gallon) for each 
    vehicle, and displays mileage for each vehicle.
    
    
    Bring a printout of your main.cpp
     file to class.  Email the main.cpp files to
     me but as you do that change the name to:  name_program5.cpp
     where name represents your last name.  And between name and
     program5 is an underscore.  I appreciate not having spaces
     in your file names.
