 8.7 Searching Exercises
 =======================
 
    • Write an interactive function that searches for a string.  If the
      search finds the string, leave point after it and display a message
      that says “Found!”.  (Do not use ‘search-forward’ for the name of
      this function; if you do, you will overwrite the existing version
      of ‘search-forward’ that comes with Emacs.  Use a name such as
      ‘test-search’ instead.)
 
    • Write a function that prints the third element of the kill ring in
      the echo area, if any; if the kill ring does not contain a third
      element, print an appropriate message.
