Tomboy toml dom

For those who are struggling with Rust's cool syntax, our goal is to provide a TOML parser that's as easy as pointing to a menu and eating fast food.
Rustのイケてる構文に難儀している人のために、メニューを指差してファーストフードを食べるぐらい簡単な操作のTOMLパーサーを提供することを目標とします。

Unstable version. It's a tryal and error process. Specifications will change.
不安定版。 試行錯誤中です。 仕様はコロコロ変わるでしょう。

Tomboy is a pun.
トムボーイ（おてんば娘）は語呂合わせです。
