		distorted.  For Layouts which will often

		-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

      -setEditable(bool): Determine whether
      the user can type in the ComboBox
      or if it is uneditable.  In this
      case, it is set to false.

      When creating a non-editable ComboBox,
      a Renderer must also be assigned.  For
      editable ComboBoxes, the ComboBox
      automatically shows its text due to the
      nature of the ComboBox.  However, when
      uneditable, this aspect of the ComboBox
      is disabled, and so to display the 
      selection, a renderer must be created and
      assigned to the ComboBox.

Note: as with Sliders and ScrollBars,
having the same Model assigned causes
the ComboBoxes to be tied together.
