 It would be convenient to be able to bind, unbind and trigger `api.Value`
 instances by event id, instead of using only functions param like it's the
 case now.

 The `api.Values` constructor is already extended with the `api.Events`
 manager object, which is very useful. I propose to do something similar
 with the `api.Value` constructor.

 In order to not overload the `api.Value.topics` object with anonymous
 functions, a possible optimization would be to fallback on the previous
 binding method of `api.Value`, with a function type param directly added
 to the `api.Value.callbacks` ( `$.Callbacks` ) object, if no id is
 provided for the callback, and to populate the `api.Value.topics` property
 only when an id has been provided on binding.
