Q5
 In Tutorial #3: Procedures, right before "What's next?" at the end there
are the following questions:
 Finally, what other slider could you add to vary how often grass grows
back?
 Are there rules you can add to the movement of the turtles or to the newly
hatched turtles that happen only at certain times?
 Q5: Add code to answer both questions. Document your additions by
comments alongside the code, AS WELL AS in the Information tab.
(so you have to figure out how it works.)
 The best way to do this is to follow the instructions step by step, so
you understand everything!
 Name your program: Q5-YourLastName-Tut3.
 Drop it into the dropbox by class on Wednesday, March 3.
