Bogus 5.1.1-beta-3

A simple and sane data generator for populating objects that supports different locales. A delightful port of the famed faker.js and inspired by FluentValidation. Use it to create and load databases and UIs with mockup data. Get started by using Faker class or a DataSet directly.

No packages depend on Bogus.
