// E.g. I need to fake name and language fields
String language;
String name;

// 1. In order to get language I need to get random value from nation.yml:
FakeValuesService fakeValuesService = new FakeValuesService(Locale.US, new RandomService()); // First FakeValueService initialisation
language = fakeValuesService.fetchString("nation.language");

// 2. In order to get name I want to utilise Faker 'facade'
Faker faker = new Faker(); // Here Faker constructor will initialise another instance of FakeValueService whilst it could allow passing FVS instance we already have initialised, e.g. like: new Faker(fakeValueService)
name = faker.name().firstName();
