Changements

Return Observable<String> instead of ObservableValue<String> for
TextBinding
Some text bindings used <some snapshot>.toObservableList and the
subscriptions were not disposed. This way of doing things allows
disposing subscriptions when a DOM node is destroyed.

gs-todomvc: Remove import of missing class
 (commit: b6a125a)

gs-reactor: Use Observables to define metabindings
– Use Observable<Snapshot<Generic>> to define a forEach and
 Observable<Optional<Context>> to define a select metabinding.
– Adapt the existing applications to this change.
– Allow sorting of Snapshots.
– Dispose subscriptions to the observables used in metabindings.

gs-todomvc: Some simplifications, add hidden styleClass when appropriate
Hide the footer if there is no todo, and the link to clear the completed
todos if there is no completed todo. The former version of the bindings
did not work because they used the “hide” CSS class but the class has
been renamed to
“hidden” in the CSS file.

gs-todomvc: Rename most tag classes, delete some
 (commit: dd1e91d)

gs-reactor: Use Observable<Boolean> to define TagSwitcher
 (commit: d534c26)

Do not return ObservableValues in methods in DefaultCompositeInheritance
Return Observable<Optional<T>> instead of ObservableValue<T> for 
getObservableAttribute, getObservableHolder, etc.
To return an ObservableValue, it’s necessary to use the
toObservableList() method from Snapshot, which is deprecated since it
does not allow unsubscription from the Observables subscribed to in the
method.
Emit items of type Optional<T> rather than T because Observables can’t
emit nulls.

gs-reactor: Refactor
Remove ObservableValue/ObservableList from functional interface names
whose functions don’t return ObservableValues/ObservableLists.

gs-todomvc: Fix bug when removing a checked item
The removal of the completion holder with value true caused the creation
of a holder with value false that prevented deletion of the item.
