/** Use JWS to modify MyApplet15.java (previously Neko.java 
 ** on pp. 236-238 of the text) so that Neko has a more unusual 
 ** (weird?) behavior or a more interesting background image or
 ** color chosen by you. Note that since the Neko images aren't
 ** nicely cropped, they carry a white square with them. So, one
 ** possibility would be to create a maze with a colored background
 ** and white paths. Also, edit MyApplet15.html in the project 
 ** directory, both to run the MyApplet15.class file you create,
 ** and so that everything looks nice and works properly.        **/
