        Create Flow Layout.  Flow Layout arranges objects
        automatically within the Frame, so that depending 
        on Frame size, the objects may appear in a vertical
        line, horizontal line, or multiple lines.  Objects 
        fill from the upper left hand corner of the Frame
        across, then down (when the line becomes full) while
        arranged Horizontally, or from the upper left hand
        corner across when arranged Vertically, starting a 
        new column when necessary.

        You can experiment with this by changing the window 
        size, changing the orientation, changing the 
        PreferredSize of the Buttons, or adding more 
		Buttons to the view.

        Note that if the Frame is too small or resized
		too much, the FlowLayout will become slightly
		distorted.  For Layouts which will often
		be dynamically changed, FlowLayout is not
		the best choice.
	
		-setHorizontalGap(int): Determine the Horizontal
			gap in pixels between Components in 
			FlowLayout.
		-setVerticalGap(int): Determine the Vertical
			gap in pixels between Components in 
			FlowLayout.
		-setOrientation(ENUM): Determine whether the
			Layout is arranged Vertically or
			Horizontally.  Takes HORIZONTAL_ORIENTATION
			or VERTICAL_ORIENTATION arguments.
		-setMajorAxisAlignment(ENUM): Determines
			the alignment of the entire Layout 
			within its ComponentContainer.  See below.
		-setMinorAxistAlignment(ENUM): Determines
			the alignment of Components within
			the Layout.  See below.

		Both of the last two functions take the
		following arguments: AXIS_MAX_ALIGNMENT, 
		AXIS_CENTER_ALIGNMENT, and AXIS_MIN_ALIGNMENT.
		MAX puts it to the bottom/right, CENTER
		centers it, and MIN puts it to the
		top/left (for Vertical/Horizontal as
		set above, respectively).

      Create Components to add to MenuBar
      Menus.  Each MenuBar has multiple Menus 
      which contain multiple MenuItems.

      -setAcceleratorKey(KeyEvent::KEY_*): This
      links the key "*" as a shortcut to 
      selecting the item it is attached to.
      An example of this would be Q with 
      Control+Q causing programs to quit.
      -setAcceleratorModifiers(KeyEvent::KEY_MODIFIER_*):
      This adds the "*" key as another 
      requirement to cause the item to be
      selected.  Things such as "CONTROL" are 
      likely to be used here (as mentioned 
      above, both Control and Q are specified).

Note: These shortcuts will be shown in the list
with the MenuItem they are attached to.

-setMnemonicKey(KeyEvent::KEY_****): sets the key
"****" to be underlined within the Menu
itself
