 * ==TBResources Snippet==
 * 
 * This snippet class lets you inject FoBo Bootstrap 2.x resources into your templates.
 * Instead of hand write the resource tags you can use this helper snippet to inject it for you.   
 * 
 * '''Example''' Invoke with 
 * {{{ data-lift="FoBo.TBResources.functionName?paramName=paramValue&...." }}} 
 * For more examples see the individual transform functions.
 * @since v1.3
