  # Initialize is called whenever any object is make. It's built into ruby to do
  # that, so this is where you would put everything to set up what you're making.
  # In this case, we call this window's superclass, which we see above is
  # Window_HorzCommand (Horizontal command window). It needs to know where to place
  # the window, so we use the variables x and y, which we got when the object was
  # originally made.
  # Then we check if the Window_Skin variable is "" (empty). If it is, don't do
  # anything. If it is different though, use that as our window skin. Then we
  #use self.width = blah to change how wide the window is. We want all the windows
  # to be the same width, so we use the same variable (Technically, variables that
  # start with capital letters are constants, we're not allowed to change them,
  # though there is *technically* a way to).
  # Next we call the refresh method, and then update the cursor.
  #
  # The refresh method is not in this class, so where is it? Kind of like when we
  # called super in initialize, if we don't define a method in out class, and then
  # some other script calls this method (such as refresh), we see if the superclass
  # has it. If it does, we do that, if not, check its superclass. This keeps going
  # until we find the method or we run out of classes, in which case we'll get an
  # error saying we can't find this method.
  # These types of errors are 'undefined local variable or method `something' for
  # MyClass:0xItsMemoryAddress.
