// * Version: 1.0.1
// * Note: Requires jquery 1.2 or above from version 1.0.1
// */

///**
// * Creates a carousel-style navigation widget for images/any-content from a simple HTML markup.
// *
// * The HTML markup that is used to build the carousel can be as simple as...
// *
// *  <div class="carousel">
// *      <ul>
// *          <li><img src="image/1.jpg" alt="1"></li>
// *          <li><img src="image/2.jpg" alt="2"></li>
// *          <li><img src="image/3.jpg" alt="3"></li>
// *      </ul>
// *  </div>
// *
// * As you can see, this snippet is nothing but a simple div containing an unordered list of images.
// * You don't need any special "class" attribute, or a special "css" file for this plugin.
// * I am using a class attribute just for the sake of explanation here.
// *
// * To navigate the elements of the carousel, you need some kind of navigation buttons.
// * For example, you will need a "previous" button to go backward, and a "next" button to go forward.
// * This need not be part of the carousel "div" itself. It can be any element in your page.
// * Lets assume that the following elements in your document can be used as next, and prev buttons...
// *
// * <button class="prev">&lt;&lt;</button>
// * <button class="next">&gt;&gt;</button>
// *
// * Now, all you need to do is call the carousel component on the div element that represents it, and pass in the
// * navigation buttons as options.
// *
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev"
// * });
// *
// * That's it, you would have now converted your raw div, into a magnificient carousel.
// *
// * There are quite a few other options that you can use to customize it though.
// * Each will be explained with an example below.
// *
// * @param an options object - You can specify all the options shown below as an options object param.
// *
// * @option btnPrev, btnNext : string - no defaults
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev"
// * });
// * @desc Creates a basic carousel. Clicking "btnPrev" navigates backwards and "btnNext" navigates forward.
// *
// * @option btnGo - array - no defaults
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      btnGo: [".0", ".1", ".2"]
// * });
// * @desc If you don't want next and previous buttons for navigation, instead you prefer custom navigation based on
// * the item number within the carousel, you can use this option. Just supply an array of selectors for each element
// * in the carousel. The index of the array represents the index of the element. What i mean is, if the
// * first element in the array is ".0", it means that when the element represented by ".0" is clicked, the carousel
// * will slide to the first element and so on and so forth. This feature is very powerful. For example, i made a tabbed
// * interface out of it by making my navigation elements styled like tabs in css. As the carousel is capable of holding
// * any content, not just images, you can have a very simple tabbed navigation in minutes without using any other plugin.
// * The best part is that, the tab will "slide" based on the provided effect. :-)
// *
// * @option mouseWheel : boolean - default is false
// * @example
// * $(".carousel").jCarouselLite({
// *      mouseWheel: true
// * });
// * @desc The carousel can also be navigated using the mouse wheel interface of a scroll mouse instead of using buttons.
// * To get this feature working, you have to do 2 things. First, you have to include the mouse-wheel plugin from brandon.
// * Second, you will have to set the option "mouseWheel" to true. That's it, now you will be able to navigate your carousel
// * using the mouse wheel. Using buttons and mouseWheel or not mutually exclusive. You can still have buttons for navigation
// * as well. They complement each other. To use both together, just supply the options required for both as shown below.
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      mouseWheel: true
// * });
// *
// * @option auto : number - default is null, meaning autoscroll is disabled by default
// * @example
// * $(".carousel").jCarouselLite({
// *      auto: 800,
// *      speed: 500
// * });
// * @desc You can make your carousel auto-navigate itself by specfying a millisecond value in this option.
// * The value you specify is the amount of time between 2 slides. The default is null, and that disables auto scrolling.
// * Specify this value and magically your carousel will start auto scrolling.
// *
// * @option speed : number - 200 is default
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      speed: 800
// * });
// * @desc Specifying a speed will slow-down or speed-up the sliding speed of your carousel. Try it out with
// * different speeds like 800, 600, 1500 etc. Providing 0, will remove the slide effect.
// *
// * @option easing : string - no easing effects by default.
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      easing: "bounceout"
// * });
// * @desc You can specify any easing effect. Note: You need easing plugin for that. Once specified,
// * the carousel will slide based on the provided easing effect.
// *
// * @option vertical : boolean - default is false
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      vertical: true
// * });
// * @desc Determines the direction of the carousel. true, means the carousel will display vertically. The next and
// * prev buttons will slide the items vertically as well. The default is false, which means that the carousel will
// * display horizontally. The next and prev items will slide the items from left-right in this case.
// *
// * @option circular : boolean - default is true
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      circular: false
// * });
// * @desc Setting it to true enables circular navigation. This means, if you click "next" after you reach the last
// * element, you will automatically slide to the first element and vice versa. If you set circular to false, then
// * if you click on the "next" button after you reach the last element, you will stay in the last element itself
// * and similarly for "previous" button and first element.
// *
// * @option visible : number - default is 3
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      visible: 4
// * });
// * @desc This specifies the number of items visible at all times within the carousel. The default is 3.
// * You are even free to experiment with real numbers. Eg: "3.5" will have 3 items fully visible and the
// * last item half visible. This gives you the effect of showing the user that there are more images to the right.
// *
// * @option start : number - default is 0
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      start: 2
// * });
// * @desc You can specify from which item the carousel should start. Remember, the first item in the carousel
// * has a start of 0, and so on.
// *
// * @option scrool : number - default is 1
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      scroll: 2
// * });
// * @desc The number of items that should scroll/slide when you click the next/prev navigation buttons. By
// * default, only one item is scrolled, but you may set it to any number. Eg: setting it to "2" will scroll
// * 2 items when you click the next or previous buttons.
// *
// * @option beforeStart, afterEnd : function - callbacks
// * @example
// * $(".carousel").jCarouselLite({
// *      btnNext: ".next",
// *      btnPrev: ".prev",
// *      beforeStart: function(a) {
// *          alert("Before animation starts:" + a);
// *      },
// *      afterEnd: function(a) {
// *          alert("After animation ends:" + a);
// *      }
// * });
// * @desc If you wanted to do some logic in your page before the slide starts and after the slide ends, you can
// * register these 2 callbacks. The functions will be passed an argument that represents an array of elements that
// * are visible at the time of callback.
