One of the "fun" things that I learned with this homework is making a custom class. I made a "GenericButton" class that would scale up
the movieclip on mouse over and scale it back down on the mouse out. Another "fun" thing that I learned was making a custom cursor
depending whether the cursor is over a character or over a sign.
Orignally I wanted to make custom classes for characters and road signs so that whenver the cursor was over a symbol of that class
the cursor itself would change it's keyframe. However, I had difficulty in making the custom class be able to access the information in
the cursor.
So instead, I gave each sign and character an instance name and added event listeners in the code to trigger the cursor keyframe switch.
