 *
 * The first goal is not performance of loading (still it should
 * allow the display of a message while loading) but on ease of
 * use and extensibility (i.e., includedeck does not need to know
 * about all existing extensions, even if by default it does know
 * some of them).

The deck.core module provides all the basic functionality for creating and
moving through a deck.  It does so by applying classes to indicate the state of
the deck and its slides, allowing CSS to take care of the visual representation

its state, as well as basic key bindings for going to the next and previous
slides.  More functionality is provided by wholly separate extension modules
that use the API provided by core.

  The default settings object for a deck. All deck extensions should extend
  this object to add defaults for any of their options.

  options.classes.after
    This class is added to all slides that appear after the 'next' slide.

  options.classes.before
    This class is added to all slides that appear before the 'previous'
    slide.

  options.classes.childCurrent
    This class is added to all elements in the DOM tree between the
    'current' slide and the deck container. For standard slides, this is
    mostly seen and used for nested slides.

  options.classes.current
    This class is added to the current slide.

  options.classes.loading
    This class is applied to the deck container during loading phases and is
    primarily used as a way to short circuit transitions between states
    where such transitions are distracting or unwanted.  For example, this
    class is applied during deck initialization and then removed to prevent
    all the slides from appearing stacked and transitioning into place
    on load.

  options.classes.next
    This class is added to the slide immediately following the 'current'
    slide.

  options.classes.onPrefix
    This prefix, concatenated with the current slide index, is added to the
    deck container as you change slides.

  options.classes.previous
    This class is added to the slide immediately preceding the 'current'
    slide.

  options.selectors.container
    Elements matched by this CSS selector will be considered the deck
    container. The deck container is used to scope certain states of the
    deck, as with the onPrefix option, or with extensions such as deck.goto
    and deck.menu.

  options.selectors.slides
    Elements matched by this selector make up the individual deck slides.
    If a user chooses to pass the slide selector as the first argument to
    $.deck() on initialization it does the same thing as passing in this
    option and this option value will be set to the value of that parameter.

  options.keys.next
