Assignment for Thu 10/15:
------------------------

(1) Do exercises 4.5 and 4.6 from the Java packet.
(2) Read Chapters 3-5 from _I, Robot_.

------------------------

-We talked about encapsulation and writing our own methods
-We introduced these ideas using Robozzle:  http://www.robozzle.com/
 -We went over the tutorials in class (we saw one reason why recursion is useful)
 -We broke up into groups to do "The Windmill"
 -We talked a little about "Binary" (hard)

-We then wrote a Java program to emulate the Robozzle language
 -The ultimate goal is to get an NXT to follow the commands, but
  our initial program simply printed the commands followed instead
 -We saw how we could create our own methods in Java
 -We saw how to call various methods (of a single object) from within one another
 -We saw how we could recursively call a method: e.g.

  public void F1 () {
    right(); // call the right method on this object
    left();  // call the left method on this object
    F1();    // call F1 from within F1, to effectively repeat the above infinitely
  }

  We notice that when calling a method of the same class, we do not need the "."
  notation to specify the object/class.
