         * Returns an object of name-value pairs that represents values in a form.  
         * It is able to nest values whose element's name has square brackets.
         * 
         * When convert is set to true strings that represent numbers and booleans will
         * be converted and empty string will not be added to the object. 
         * 
         * Example html:
         * @codestart html
         * <form>
         *   <input name="foo[bar]" value='2'/>
         *   <input name="foo[ced]" value='4'/>
         * <form/>
         * @codeend
         * Example code:
         * 
         *     $('form').formParams() //-> { foo:{bar:'2', ced: '4'} }
         * 
         * 
         * @demo jquery/dom/form_params/form_params.html
         * 
         * @param {Object} [params] If an object is passed, the form will be repopulated
         * with the values of the object based on the name of the inputs within
         * the form
         * @param {Boolean} [convert=false] True if strings that look like numbers 
         * and booleans should be converted and if empty string should not be added 
         * to the result. Defaults to false.
         * @return {Object} An object of name-value pairs.
