code: function one(callback) {
          ///<summary>Execute a callback only once</summary>
          callback = callback || noop;
  
          if (callback._done) {
              return;

      }
docs: INFO: this look like a "im triggering callbacks all over the place, but only wanna run it one time function" ..should try to make everything work without it if possible INFO: Even better. Look into promises/defered's like jQuery is doing
