* Provides access to deserializers.
*
* This plugin point allows instances to {@link SerDeserializer} to be created.
* Implementations of this interface can introspect the bean type when choosing a deserializer.
* This allows deserializers to be provided that can handle multiple bean types, for example all beans
* in a particular package, any bean with a particular supertype or with a particular annotation.
*
* In the simple case where an exact match is needed, the class implementing {@link SerDeserializer}
* can also implement {@link SerDeserializerProvider} with a singleton constant instance.
