This method moves and resizes the bar so that it will lay along the edge of the screen specified by the position value -- None, Left, Right, Top, or Bottom. It asks NXApp for the current screen size, so that it can adjust to different size screens. The bar also checks the floatActivator global variable to see which window tier it should display in. If floatActivator is YES, the bars will be shown in the same tier as the standard Dock (tier 5). Otherwise, they will be in the standard window tier (tier 0).
