/**

* @name toggler
* @version 0.2
* @author teramako <teramako at gmail.com>
* ==/VimperatorPlugin==
*
* 何かしらの設定をクルクル変更したい人へ
*
* まず、最初に以下の例ように.vimperatorrcに定義する
js <<EOM
liberator.globalVariables.toggler = {
name: [ setting commands ]],
go: ["set go=","set go=m","set go=b"],
sb: ["sbclose","sbar Console"],
go_and_sb: [
["set go=","sbclose"],
["set go=mTb","sbar Console"]
],
//...
};
EOM
*
* 次に
* :toggle go
* とコマンドを実行するとsetting commands配列の次を実行する
* 最後までいくと最初に戻る
* つまり、最初に :toggle go をすると set go=m が実行される
* もう一度実行すると、set go=b が実行される
* もう一度すると、最初に戻って、set go= が実行される
*
* :map <F2> :toggle go<CR>
* などとやっておくとボタン一つでクルクル替わる
