* The first goal is not performance of loading (still it should

* 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
of each state. It also provides methods for navigating the deck and inspecting
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.

event will never be fired and the slide will not change.

calling lockInit on the event object passed to this event. The init can be

/*
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
The numeric keycode used to go to the next slide.
options.keys.previous
The numeric keycode used to go to the previous slide.
options.touch.swipeDirection
The direction swipes occur to cause slide changes. Can be 'horizontal',
'vertical', or 'both'. Any other value or a falsy value will disable
swipe gestures for navigation.
options.touch.swipeTolerance
The number of pixels the users finger must travel to produce a swipe
gesture.
options.initLockTimeout
The number of milliseconds the init event will wait for BeforeInit event
locks to be released before firing the init event regardless.
options.hashPrefix
Every slide that does not have an id is assigned one at initialization.
Assigned ids take the form of hashPrefix + slideIndex, e.g., slide-0,
slide-12, etc.
options.preventFragmentScroll
When deep linking to a hash of a nested slide, this scrolls the deck
container to the top, undoing the natural browser behavior of scrolling
to the document fragment on load.
options.setAriaHiddens
When set to true, deck.js will set aria hidden attributes for slides
that do not appear onscreen according to a typical heirarchical
deck structure. You may want to turn this off if you are using a theme
where slides besides the current slide are visible on screen and should
be accessible to screenreaders.

/*
Extends defaults/options.
options.designWidth
Defaults to 800. You may instead specify a width as a number
of px and all slides will be scaled in the same way, considering their
size is the provided one.
options.designHeight
Defaults to 600. You may instead specify a height as a number
of px and all slides will be scaled in the same way, considering their
size is the provided one.
options.fitMode
How to adapt the slide to the container.
Only the following combinations are available for now:
"center middle", "top left", "bottom right", "stretched"
options.fitMarginX
options.fitMarginY
Defaults to 5. Adds some margin in design space units.
E.g., if the designe width is 800 and the margin is 5, the slide will be
810 pixel wide before rescaling.
options.scaleDebounce
Scaling on the browser resize event is debounced. This number is the
threshold in milliseconds. You can learn more about debouncing here:
