  10  * jGrowl is a jQuery plugin implementing unobtrusive userland notifications.  These
  11  * notifications function similarly to the Growl Framework available for
  12  * Mac OS X (http://growl.info).
  13  *
  14  * To Do:
  15  * - Move library settings to containers and allow them to be changed per container
  16  *
  17  * Changes in 1.2.0
  18  * - Added message pooling to limit the number of messages appearing at a given time.
  19  * - Closing a notification is now bound to the notification object and triggered by the close button.
  20  *
  21  * Changes in 1.1.2
  22  * - Added iPhone styled example
  23  * - Fixed possible IE7 bug when determining if the ie6 class shoudl be applied.
  24  * - Added template for the close button, so that it's content could be customized.
  25  *
  26  * Changes in 1.1.1
  27  * - Fixed CSS styling bug for ie6 caused by a mispelling
  28  * - Changes height restriction on default notifications to min-height
  29  * - Added skinned examples using a variety of images
  30  * - Added the ability to customize the content of the [close all] box
  31  * - Added jTweet, an example of using jGrowl + Twitter
  32  *
  33  * Changes in 1.1.0
  34  * - Multiple container and instances.
  35  * - Standard $.jGrowl() now wraps $.fn.jGrowl() by first establishing a generic jGrowl container.
  36  * - Instance methods of a jGrowl container can be called by $.fn.jGrowl(methodName)
  37  * - Added glue preferenced, which allows notifications to be inserted before or after nodes in the container
  38  * - Added new log callback which is called before anything is done for the notification
  39  * - Corner's attribute are now applied on an individual notification basis.
  40  *
  41  * Changes in 1.0.4
  42  * - Various CSS fixes so that jGrowl renders correctly in IE6.
  43  *
  44  * Changes in 1.0.3
  45  * - Fixed bug with options persisting across notifications
  46  * - Fixed theme application bug
  47  * - Simplified some selectors and manipulations.
  48  * - Added beforeOpen and beforeClose callbacks
  49  * - Reorganized some lines of code to be more readable
  50  * - Removed unnecessary this.defaults context
  51  * - If corners plugin is present, it's now customizable.
  52  * - Customizable open animation.
  53  * - Customizable close animation.
  54  * - Customizable animation easing.
  55  * - Added customizable positioning (top-left, top-right, bottom-left, bottom-right, center)
  56  *
  57  * Changes in 1.0.2
  58  * - All CSS styling is now external.
  59  * - Added a theme parameter which specifies a secondary class for styling, such
  60  *   that notifications can be customized in appearance on a per message basis.
  61  * - Notification life span is now customizable on a per message basis.
  62  * - Added the ability to disable the global closer, enabled by default.
  63  * - Added callbacks for when a notification is opened or closed.
  64  * - Added callback for the global closer.
  65  * - Customizable animation speed.
  66  * - jGrowl now set itself up and tears itself down.
  67  *
  68  * Changes in 1.0.1:
  69  * - Removed dependency on metadata plugin in favor of .data()
  70  * - Namespaced all events
