Added a number of changes:

-Changed how databases are input into the script
	-Added loop to compare databases
		-Script will terminate if databases are lacking
                 the same tables as the main database
	-Added check to see if user added databases and will terminate if not
	-Added loop to attach databases so the user does not have to
