+/**
+ * Provides algorithms for normalization of labeled trees.
+ *  Normalization transforms an input labeled tree, where some nodes have non-empty
+ *  property collections (i.e., nodes for which the method {@code getProperties()} returns
+ *  a non-empty map), into an unlabeled tree. In the resulting tree, all properties are
+ *  individually moved to special leaf nodes. Each leaf node's type represents the property name,
+ *  and its data represents the property value.
+ * @since 2.0.0
