The ultimate TOML library for Java 8+.
Goals are feature completeness and a permissive yet type-safe API.
JToml supports the latest version of the TOML spec (v1.0.0).
TOML is a first-class citizen; no casts, no wonky date-time handling,
no dependencies. Working with keys is fluid and unambiguous with
methods for parsing, slicing and joining.
