+/**
+ * I LOVE :echo
+ * I LOVE :js
+ *
+ * 説明
+ * :echo コマンドが大好きな人用
+ * とにかく、ワンラインでタブ補完しつつコード実行をするためのネタ的プラグイン
+ *
+ * 完成度は低い
+ *
+ *  設計思想
+ *   *  最初に与えた引数を変換に変換を重ねてコネくり回すことが主眼
+ *   *  各メソッドやgetterは常にvalue(またはxhr)メンバを持つObject
+ *   *  メソッドやgetterはvalue値に相応しいメソッドまたはgetterである
+ *
+ * 
+ * Example:
+ *        1                                        2      3      4   5        6          7                               8
+ *  :echo $x("http://d.hatena.ne.jp/teramako/rss").open().send().xml.toObject.get("item").map(function(item) item.title).value
+ *  ブログのRSSをゲットしてオブジェクト化して、各item要素内のtitle文字列を格納した配列をechoする
+ *
+ *  1. $xにURLを渡し
+ *  2. XMLHttpRequest.open()し
+ *  3. リクエストを送信し
+ *  4. レスポンスをDOMオブジェクトを得て(XMLHttpRequest.responseXML)
+ *  5. さらにObject化し(toObjectはXMLのタグ名をキーにツリー構造を模したObject)
+ *  6. オブジェクト内の"item"メンバ(配列)を得て
+ *  7. map関数で各item内のtitleを得て
+ *  8. その値 :echo に渡す(RSSのタイトル一覧の出力となる)
+ *
+ *  :js $_.url.MD5Hash.copy()
+ *  現在開いているURLのMD5ハッシュ値をクリップボードにコピー
+ *
+ *  :js $x("http://example.com").open().send().xml.stack()
+ *   とりあえず、http://exapmle.comのDOMドキュメントをstack
+ *  :echo $_.cache.last.inspect()
+ *   最後にstackしたものを取り出し、DOM Inspectorに出力(DOM Inspectorが入っている場合)
