Minimal JSON parser which works with correct input only

	// Minimal JSON parser which works with correct input only.
	// Usecase:
	// 1. Walk through unstructured json
	// 2. Transform unstructured json
	// without fully unmarshalling it into a map[string]interface{}
	//
	// Caution: Behaviour is undefined on invalid json. Use on trusted input only.
