 83 tlrkSlider
 84   
 85   example usage:
 86  
 87     $("#slider").tlrkSlider({
 88       autoStart: false,
 89       elements: {
 90         "img": {delay: 10},
 91         "h2": {delay: 500},
 92         ".copy": {delay: 800},
 93         ".button": {delay: 1000}
 94       }
 95     });
 96 
 97   to go to a specific frame:
 98     $("#slider").tlrkSlider("go", position);
 99     "position" can have one of the following values:
100     "next", "prev", "first", "last", "+1", "-1" or a numeric value
101   
102   to start/stop the automatic loop:
103     $("#slider").tlrkSlider("start");
104     $("#slider").tlrkSlider("stop");
105   
106   to change the delay between automatic transitions:
107     $("#slider").tlrkSlider("option", "delayAnimation", 1000);
108  
109   to change any option:
110     $("#slider").tlrkSlider("option", option_name, option_value);
111     
112   Changing the "elements" object is not tested.
113   
114   Changing the following options: "navigation", "navigationClass", "framesSelector", "autoStart" won't have any effect for now.
115   They are used only during the initialization.
116   
117   $("#slider").data("tlrkSlider") will return the plugin instance and the methods/properties can be accessed from there.
118   
119   The plugin contructor defaults are accessable through TlrkSlider.defaults
120   
121   The function that actually sweep the elements in/out can be overriden from
122     TlrkSlider.prototype._animationIn and TlrkSlider.prototype._animationOut
