nl_tokens: Adds extend and extendWith static methods to the passed in constructor for having easy extensibility via said methods ; I . e . passed in constructor will now be extendable via added methods .

           * @param statics {Object|undefined} - Static methods.  Optional.  Note:  If `constructor` param is an object, it is not used.
