/**
 *  This JQuery Plugin will help you in showing some nice Toast-Message like notification messages. The behavior is
 *  similar to the android Toast class.
 *  You have 4 different toast types you can show. Each type comes with its own icon and colored border. The types are:
 *  - notice
 *  - success
 *  - warning
 *  - error
 *
 *  The following methods will display a toast message:
 *
 *   $().toastmessage('showNoticeToast', 'some message here');
 *   $().toastmessage('showSuccessToast', "some message here");
 *   $().toastmessage('showWarningToast', "some message here");
 *   $().toastmessage('showErrorToast', "some message here");
 *
 *   // user configured toastmessage:
 *   $().toastmessage('showToast', {
 *      text     : 'Hello World',
 *      sticky   : true,
 *      position : 'top-right',
 *      type     : 'success',
 *      close    : function () {console.log("toast is closed ...");}
 *   });
 *
 *   To see some more examples please have a look into the Tests in src/test/javascript/ToastmessageTest.js
 *
 *   For further style configuration please see corresponding css file: jquery-toastmessage.css
 *
 *   This plugin is based on the jquery-notice (http://sandbox.timbenniks.com/projects/jquery-notice/)
 *   but is enhanced in several ways:
 *
 *   configurable positioning
 *   convenience methods for different message types
 *   callback functionality when closing the toast
 *   included some nice free icons
 *   reimplemented to follow jquery plugin good practices rules
