jQuery Stringify

jquery.stringify.js

/**
 * jQuery.stringify (https://gist.github.com/953765)
 * 
 * converted stringify() to jQuery plugin.
 * serializes a simple object to a JSON formatted string.
 * uses browser's native JSON.stringify() if it exists. 
 * Note: stringify() is different from jQuery.serialize() which URLEncodes form elements
 *
 * UPDATES:
 *      Added a fix to skip over Object.prototype members added by the prototype.js library
 * USAGE:
 *  jQuery.ajax({
 *	    data : {serialized_object : jQuery.stringify (JSON_Object)},
 *		success : function (data) {
 *			...
 *		}
 *   });
 *
