nl_tokens: Calls promisify on all valid functions on a module . Ignores certain properties on a modules so the return values is not polluted . ( This can be configured by passing in a filter function via opts . isValid . )

                       * Filter out functions that aren't 'public' and aren't 'methods' and aren't asynchronous.
                       *  This is mostly educated guess work based on de facto naming standards for js.
                       *
                       * e.g.
                       *      valid:        'someFunctionName' or 'some_function_name' or 'someFunctionAsync'
                       *      not valid:    'SomeConstructor' or '_someFunctionName' or 'someFunctionSync'

                       *  As there may be exceptions to these rules for certain modules,
                       *   you can pass in a function via opts.isValid which will override this.
