      The alignment configuration for this widget.
  
      The `align` attribute is used to align a reference point on the widget, with
      the reference point on another `Node`, or the viewport. The object which
      `align` expects has the following properties:
  
        * __`node`__: The `Node` to which the widget is to be aligned. If set to
          `null`, or not provided, the widget is aligned to the viewport.
      
        * __`points`__: A two element Array, defining the two points on the widget
          and `Node`/viewport which are to be aligned. The first element is the
          point on the widget, and the second element is the point on the
          `Node`/viewport. Supported alignment points are defined as static
          properties on `WidgetPositionAlign`.
      
      @example Aligns the top-right corner of the widget with the top-left corner 
      of the viewport:
  
          myWidget.set('align', {
              points: [Y.WidgetPositionAlign.TR, Y.WidgetPositionAlign.TL]

      Attribute.
      
      If set to `true`, the widget is centered in the viewport. If set to a `Node` 
      reference or valid selector String, the widget will be centered within the 
      `Node`. If set to `false`, no center positioning is applied.
