/**
 * The fdd2div() method provides a simple way of converting form drop down <select> into <div>.  
 *
 * fdd2div() takes 2 string and 2 integer argument:  $().fdd2div({css class name, open status of the menu, create html hyper links, animation speed})
 *
 *   CssClassName: It will take the css class name or it will take the class name from the <div>. 
 *                   If you don't specify an css class, default css will be used.
 *
 *   OpenStatus: It will be let the menu open or close. By default it will be closed. 1 for open and 0 for closed
 *
 *   GenerateHyperlinks: If you want hyperlink to act exactly as form than leave this one, otherwise it will take 1 and will use the form's>select's>option's value as a page name
 *                                           If there is no <option>'s value than it will take anything in between <option></option> as value                                               
 *                               So the if the url is www.mukuru.com/test.php, the new hyperlink will be www.mukuru.com/options_value.php 
 *
 *   AnimationSpeed: Use to specify the animation speed which could be either slow,normal or fast 
 *                   By default it will be normal.
 *
 *
 * @example $('#form_wrapper').fdd2div({CssClassName: "OverWrite_Default_Css_Class",OpenStatus: 1,GenerateHyperlinks: 1,AnimationSpeed: "slow"});
 * @desc Convert form drop down into div menu with css my own class (OverWrite_Default_Css_Class), menu will be open, take page name from <option> and create normal hyperlinks, animation speed show be slow 
 *
 * @example $('#form_wrapper').fdd2div();
 * @desc Convert form drop down into div menu with default css class which is (fdd2div_default), OpenStatus: 0 (closed), GenerateHyperlinks: 0 (act like form), animation speed will be normal
 *
 * @name fdd2div
 * @type jQuery
 * @param 2 String and 2 Integers Options which control the drop down menu style and status
