TickBuggle class are
buggles that handle two additional instance methods:
public void tick ()
Performs the tick action of this buggle. By default, this action is to do nothing. A non-trivial action is specified by overriding this method in a subclass ofTickBuggle.
public void tick (int n)
Performs the tick action of this bugglentimes. This is a handy way to repeat a buggle action a fixed number of times without using explicit recursion or iteration.
