// クラスとインターフェースの組み合わせを表示するためのプラグイン
//
// :lscc {class} {interface}
//
// タブ補完で遊んでください
// 第一引数はComponents.classesから正規表現にひっかかるものを補完
// 第に引数はComponents.interfacesから(ry
//
// 完全なクラスとインターフェースを入力して実行すると、
// createInstance or getService して使えそうなメソッドやメンバーを表示します
//
// 未補完でも大丈夫。適当に使えそうな組み合わせを表示してくれます
//
// 注意：あまりに組み合わせの多いクラスとインターフェースを表示しようとするとFirefox, Thunderbirdごと落ちます(ぉ
// （だれか直してー）
