/* EXAMPLE
  You can pass in an HTML string that will get rendered

  $(document.body).actionsheet('<a >Back</a><a onclick="alert(\'hi\');" >Show Alert 3</a><a onclick="alert(\'goodbye\');">Show Alert 4</a>');

  You can also use an arra of objects to show each item.  There are three propertyes
    text - the text to display
    cssClasses - extra css classes
    handler - click handler function

  $(document.body).actionsheet(
    [{
        text: 'back',
        cssClasses: 'red',
        handler: function () {
            $.ui.goBack();
        }
    }, {
        text: 'show alert 5',
        cssClasses: 'blue',
        handler: function () {
            alert("hi");
        }
    }, {
        text: 'show alert 6',
        cssClasses: '',
        handler: function () {
            alert("goodbye");
        }
    }]
  );
