    * growAlert plugin by Luke Stebner (luke.stebner@gmail.com)
    * created on 2.20.2011 | last modified 2.21.2011
    * 
    * This little plugin is used to create little alert messages in the style that Growl works. It was
    * created as a tutorial demo for programming.linnnk.com, but due to popularity I've decided to flush
    * it out into a more useful piece of code than just the basic alert functionality. 
    *
    * If you stumbled upon this piece of code and don't know where it originated, you can head over to it's
    * github location here: https://github.com/lstebner/jQuery-Growl-Alert-Plugin
    *
    * My growlAlert plugin is free for anyone to use however they see fit, though I ask that you ping me
    * back if you do anything really cool with it because I'd love to check it out and/or show it off. 
    *
    * 
    * Params:
    * @opts     <string or object>  Either a method name to call or an object of settings on initialization
    *       settings {
    *           autoShow : true/false - Show this message right away or wait for 'show' call
    *           fadeTime : milliseconds - The amount of time over which to fadeIn and fadeOut
    *           delayTime : milliseconds - The amount of time to leave the message displayed before fadeOut call
    *           title : string - The title to use for the alert
    *           content: string - The content for the growl alert
    *           closeIcon: string - The path to the image to use as the close icon
    *           onShow: function - A callback function for when the message is fully displayed
    *           onComplete: function - A callback function for when the message has disappeared (completed)
    *           position: string - Where to position the alert (top-left, top-right, bottom-left, bottom-right)
    *       }
    *       methods{
    *           - show(settings) - Show the message immediately on call 
    *               @settings   <object>    Any settings data to override immediately
    *       }
    *
    * @data     <object>            An object of data to pass with the method call specified for 'opts'
    *
