// To use this code, add the following Maven dependency to your project:
//
//     com.fasterxml.jackson.core : jackson-databind : 2.9.0
//
// Import this package:
//
//     import io.quicktype.Converter;
//
// Then you can deserialize a JSON string with
//
//     LatestBlock data = Converter.LatestBlockFromJsonString(jsonString);
//     UnconfirmedTransactions data = Converter.UnconfirmedTransactionsFromJsonString(jsonString);
