+/**
+ * A Registry which serves as a typed key:value store for Superset and for Plugins.
+ *
+ * Differences from the older Registry class:
+ *
+ * 1. The keys and values stored in this class are individually typed by TYPEMAP parameter.
+ *    In the old Registry, all values are of the same type and keys are not enumerated.
+ *    Though you can also use indexed or mapped types in a TYPEMAP.
+ *
+ * 2. This class does not have a separate async get and set methods or use loaders.
+ *    Instead, TYPEMAP should specify async values and loaders explicitly when needed.
+ *    The value can be anything! A string, a class, a function, an async function... anything!
+ *
+ * 3. This class does not implement Policies, that is a separate concern to be handled elsewhere.
+ *
+ *
+ * Removing or altering types in a type map could be a potential breaking change, be careful!
+ *
+ * Listener methods have not been added because there isn't a use case yet.
