This type class can be instantiated for any type E which can bear its
description as SchemaKey
Unlike AttachSchemaKey this type class makes possible to *only* extract
description from entity. Also it doesn't assume that type E *with*
description is the same E without it, so it can be instantiated for not
only JSON-like structures, but for case classes as well.
But in most cases these type classes can be instantiated for same types.
It particularly useful for validation/data extraction apps which need to
*extract* instance/schema description.
E
entity type, mostly intended for various JSON ADTs,
like Json4s, Jackson, circe, Argonaut etc,
but also can be anything that can bear reference to
its description like Thrift, Map[String, String] etc
