Pull Request Type
Description
Add an ability to override arbitrary atoms only for scoped view-tree.
When a scoped overridden atom is accessed from within a scope, the overridden value is returned and the state is kept in the scope, not in the root or scopes in the ancestor. If accessed from outside the scope, the unoverridden value is used and the state is kept in the root.
Scopes can be nested, with the override of the nearest scope among the ancestors taking precedence.
