code: function ComputedObjectObservationData(instance, prop, observation){
  	this.instance = instance;
      this.prop = prop;
      this.observation = observation;
  	this.forward = this.forward.bind(this);
  }
docs: ## ComputedObjectObservationData Instances of this are created to wrap the observation. The `.bind` and `.unbind` methods should be called when the instance's prop is bound or unbound.
