+/**
+ * Registry-like object which serves as a registry of registries.
+ *
+ * Registry object should implement `register` and `get; method as Singleton or
+ * Construct registry do. It's expected that there will be different types of
+ * registries for various object types.
+ *
+ * Existing registries can be access directly by properties.
+ *
+ * Use set method for setting new registry.
+ * Use get/registry method for getting/registering of object in a registry.
+ *
+ * Registries should be named by their object type in singular form.
+ * I.e.:
+ *   * entity
+ *   * widget
+ *   * action
+ *   * formatter
+ *   * facet
+ *   * dialog
