This is a major update that does not only bring along many changes to the internal architecture of the library but also to its public interface.

• Removed the TomlParser class. Use TomlDocument.parse and TomlDocument.toMap instead.
• In preparation to support TOML v0.5.0 in an upcoming version of the library, the parser is now based on TOML's official ABNF.
• Removed the TomlEncoder class. Use TomlDocument.fromMap and TomlDocument.toString instead.
• Removed the toml.decoder and toml.encoder libraries. You should always use the toml library instead.
• Removed the toml.loader library as well as the toml.loader.* libraries. Use TomlDocument.load instead. In order to implement a custom loading mechanism, use TomlDocument.parse instead.
• Removed the yaml dependency. JSON and YAML documents cannot be loaded with this package anymore.
• Renamed TomlEncodable to TomlEncodableValue and toToml to toTomlValue.
• Added TomlEncodableKey interface. Objects that implement this interface are allowed to be used as keys in hash maps instead of strings. Their toTomlKey method must return a TomlEncodeableKey itself or a string that can be used as a TOML key. By default toTomlKey is implemented via toTomlValue.
