// A simple way to get Codable comformance for [Any] and [String: Any] types,
// where Any can be any basic type as well as nested arrays and dictionaries.
//
// Use:
// let associativeStorage = [String: Any]()
// First wrap it
//      let wrappedAssociativeStorage = try AnyWrapper.wrapperFor(associativeStorage)
// Then encode it using:
//      let data = try encoder.encode(associativeStorage)
