+ * Usage:
+ *
+ * // using default options
+ * $(document).endlessScroll();
+ *
+ * // using some custom options
+ * $(document).endlessScroll({
+ *   fireOnce: false,
+ *   fireDelay: false,
+ *   loader: "<div class=\"loading\"><div>",
+ *   callback: function(){
+ *     alert("test");
+ *   }
+ * });
+ *
+ * Configuration options:
+ *
+ * bottomPixels  integer          the number of pixels from the bottom of the page that triggers the event
+ * fireOnce      boolean          only fire once until the execution of the current event is completed
+ * fireDelay     integer          delay the subsequent firing, in milliseconds, 0 or false to disable delay
+ * loader        string           the HTML to be displayed during loading
+ * data          string|function  plain HTML data, can be either a string or a function that returns a string,
+ *                                when passed as a function it accepts one argument: fire sequence (the number
+ *                                of times the event triggered during the current page session)
+ * insertAfter   string           jQuery selector syntax: where to put the loader as well as the plain HTML data
+ * callback      function         callback function, accepts one argument: fire sequence (the number of times
+ *                                the event triggered during the current page session)
+ * resetCounter  function         resets the fire sequence counter if the function returns true, this function
+ *                                could also perform hook actions since it is applied at the start of the event
+ * ceaseFire     function         stops the event (no more endless scrolling) if the function returns true
+ *
+ * Usage tips:
+ *
+ * The plugin is more useful when used with the callback function, which can then make AJAX calls to retrieve content.
+ * The fire sequence argument (for the callback function) is useful for 'pagination'-like features.
