 ruby try to call self.tick i.e. TkButton#tick and not StopWatch#tick, this
 is why it give an error

a> 			$stop = TkButton.new {	
a> 	  			text 'Stop'
a> 	  			command proc{
a> 	    			text "Zero"
a> 	    			if @@stopped then
a> 						zero

 same here, it try to call TkButton#zero and not StopWatch#zero

a> 	        			text 'Stop'
a> 	    			end
a> 	    			@@stopped = TRUE
a> 	  			}
