// JsonVal is the interface representing a Json value.
// It implements the Marshaler interface making it
// compatible with the encoding/json package.
//
// There are six types implementing JsonVal:
//   - Object
//   - Array
//   - String
//   - Number
//   - Bool
//   - Null
//
// Because JsonVal has the unexported method isJsonVal(),
// it cannot be implemented by other other types.
//
