* Make `YamlLoader` generic on the type of the `Node`. This is required because deeper node need to have annotations too. * Add a `LoadableYamlNode` trait, required for YAML node types to be loaded by `YamlLoader`. It contains methods required by `YamlLoader` during loading. * Implement `LoadableYamlNode` for `Yaml`. * Take `load_from_str` out of `YamlLoader` for parsing non-annotated nodes. This avoids every user to specify the generics in `YamlLoader::<Yaml>::load_from_str`.
