/* Select2 pattern.
 *
 * Options:
 *    separator(string): Analagous to the separator constructor parameter from Select2. Defines a custom separator used to distinguish the tag values. Ex: a value of ";" will allow tags and initialValues to have values separated by ";" instead of the default ",". (',')
 *    initialValues(string): This can be a json encoded string, or a list of id:text values. Ex: Red:The Color Red,Orange:The Color Orange  This is used inside the initSelection method, if AJAX options are NOT set. (null)
 *    vocabularyUrl(string): This is a URL to a JSON-formatted file used to populate the list (null)
 *    allowNewItems(string): All new items to be entered into the widget(true)

/*
    Usage Note:
    -----------
    Do not use both ajaxSubmit and ajaxForm on the same form.  These
    functions are mutually exclusive.  Use ajaxSubmit if you want
    to bind your own submit handler to the form.  For example,

    $(document).ready(function() {
        $('#myForm').on('submit', function(e) {
            e.preventDefault(); // <-- important
            $(this).ajaxSubmit({
                target: '#output'
            });
        });
    });

    Use ajaxForm when you want the plugin to manage all the event binding
    for you.  For example,

    $(document).ready(function() {
        $('#myForm').ajaxForm({
            target: '#output'
        });
    });

    You can also use ajaxForm with delegation (requires jQuery v1.7+), so the
    form does not have to exist when you invoke ajaxForm:

    $('#myForm').ajaxForm({
        delegation: true,
        target: '#output'
    });

    When using ajaxForm, the ajaxSubmit function will be invoked for you
    at the appropriate time.

 * 2. This method will include the submit element's name/value data (for the element that was

 * 3. This method binds the submit() method to the form for you.

/* Modal pattern.
 *
 * Options:
 *    height(string): Set the height of the modal, for example: 250px ('')
 *    width(string): Set the width of the modal, for example: 80% or 500px. ('')
 *    margin(function or integer): A function, Integer or String which will be used to set the margin of the modal in pixels. If a function is passed it must return an Integer. (20)
 *    position(string): Position the modal relative to the window with the format: "<horizontal> <vertical>" -- allowed values: top, bottom, left, right, center, middle. ('center middle')
 *    triggers(array): Add event listeners to elements on the page which will open the modal when triggered. Pass an Array of strings with the format ["&lt;event&gt; &lt;selector&gt;"] or ["&lt;event&gt;"]. For example, ["click .someButton"]. If you pass in only an event such as, ["change"], the event listener will be added to the element on which the modal was initiated, usually a link or button. ([])
 *    title(string): A string to place in the modal header. If title is provided, titleSelector is not used. (null)
 *    titleSelector(string): Selector for an element to extract from the content provided to the modal and place in the modal header. ('h1:first')
 *    content(string): Selector for an element within the content provided to the modal to use as the modal body. ('#content')
 *    prependContent(string): Selector for elements within the content provided to the modal which will be collected and inserted, by default above, the modal content. This is useful for extracting things like alerts or status messages on forms and displaying them to the user after an AJAX response. ('.portalMessage')
 *    backdrop(string): Selector for the element upon which the Backdrop pattern should be initiated. The Backdrop is a full width mask that will be apply above the content behind the modal which is useful for highlighting the modal dialog to the user. ('body')
 *    backdropOptions(object): Look at options at backdrop pattern. ({ zIndex: "1040", opacity: "0.8", className: "backdrop", classActiveName: "backdrop-active", closeOnEsc: true, closeOnClick: true })
 *    buttons(string): Selector for matching elements, usually buttons, inputs or links, from the modal content to place in the modal footer. The original elements in the content will be hidden. ('.formControls > input[type="submit"]')
 *    automaticallyAddButtonActions(boolean): Automatically create actions for elements matched with the buttons selector. They will use the options provided in actionOptions. (true)
 *    loadLinksWithinModal(boolean): Automatically load links inside of the modal using AJAX. (true)
 *    actionOptions(object): A hash of selector to options. Where options can include any of the defaults from actionOptions. Allows for the binding of events to elements in the content and provides options for handling ajax requests and displaying them in the modal. ({})
