4.0.0-alpha.1

This is the first release of configlet that is designed for Exercism v3.

The version number starts at 4.0.0-alpha.1 because the previous version of configlet (for Exercism v2) was 3.9.2. This repository is a complete rewrite in the Nim programming language. The previous codebase is now located at https://github.com/exercism/v2-configlet

Included commands:

• configlet lint, with only a small subset of the eventual linting rules.
• configlet sync, which replaces the old canonical_data_syncer functionality.
• configlet uuid

The initial rules implemented by configlet lint:

• The track config.json exists and is valid JSON
• Every concept exercise has the required .md files and a .meta/config.json file
