// MKNumberBadgeView
// -----------------
//
// Use this class to display a badge containing an integer value.Similar to the app icon badges that the iPhone OS permits.
//
// Notes:
//    * When creating the view, the frame used should be larger than the expected visual size of the badge view. Use the alignment 
//      property to control the horizontal placement of the badge within the view's bounds. The badge will always be vertically
//      centered for the badge itself ignoring the size fo the shadow if it is enabled.
//    * The view's background color is automatically set to clear. If you change the background color, you may get curious results.
//
