=========================================================================================
1. Add a print() method to your ice cream sundae class (or override operator<<) for cout.
   This method should print a message about the number of scoops and number of calories 
   in a sundae.
2. Override print() in the banana split class to have the message also include 
   number of bananas.
3. Write a separate function void print_all(const vector<sundae*> & treats) [outside of 
   the classes] that prints each sundae (or banana split).  Make three sundaes (at least 
   one should be a banana split) in main, put them in a vector, and call print_all on the 
   vector.  Make sure the output is correct.
4. Write a separate function int total_calories(const vector<sundae*> & treats) that 
   is just like print_all, but calculates and returns the total number of calories in
   a vector of pointers to sundaes.
5. For the sundae class, write a function called add_scoop() that adds one scoop of 
   ice cream to a sundae.  Write a separate function that takes a vector of sundae 
   pointers and adds a scoop to each sundae.  Use print_all to make sure your function
   works for both sundaes and banana splits.
