Your code should include:

4 functions - menu(), random_word(), remove_word(), print_list()

menu() - prints the menu choices the user can perform
random_word() - selects a random word from the list, prints the random word.
remove_word(word) - removes the word that the user wants to remove from the list.
print_list() - prints the list
Add a new function to the program:

add_word(word) - adds a word the user wants to add to the list.
Your code should continuously ask the user for a command to perform from the menu until the user is finished using your randomizer.

Your code should make sure the user can only type valid commands from the menu.
