'''
	
	Write a program that asks a user to choose a word from its list and gives the user the meaning of that word. 

	If the word entered by the user is not in the program's list, the program should alert the user that the word does not exist in the list.

	The program should ask the user whether they want to continue to search for word meanings or else type 'exit' to stop searching.
