+ 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
