This name should identify the instance (observable or observer) uniquely enough for your purposes. You can read / write it to simplify debugging. Airstream uses this in
debugLog*methods. In the future, we will expand on this. #TODO[Debug] We don't use this to its full potential yet.- Attributes

Set the display name for this instance (observable or observer).
Set the display name for this instance (observable or observer). - This method modifies the instance and returns
this. It does not create a new instance. - New name you set will override the previous name, if any. This might change in the future. For the sake of sanity, don't call this more than once for the same instance. - If display name is set, toString will output it instead of the standard type@hashcode string- Definition Classes
