   Assignment:

   Write a program which prompts the user to first enter a name, and then enter an address. 
   Your program should create a map and add the name and address to the map using the keys “name” and “address”, respectively. 
   Your program should use Marshal() to create a JSON object from the map, and then your program should print the JSON object.
