/**
* ==VimperatorPlugin==
* @name stylesheet changer
* @description enable to apply user stylesheets like Stylish
* @description-ja Stylishの様にユーザスタイルシートの適用を可能にします
* @author teramako teramako@gmail.com
* @license MPL 1.1/GPL 2.0/LGPL 2.1
* @version 0.3a
* ==/VimperatorPlugin==
*
* Usage:
*
* :hi[ghlight] [groupName] -> list all or specified group temporary-style(s)
* :hi[ghlight] clear [groupName} -> clear all or specified group temporary-styles
* :hi[ghlight] {groupName} {style...} -> define style as {groupName}
*
* :altcolo[rschema] -> list available site alternative styles (`*'-marked is current style)
* :altcolo[rschema] {altStyleName} -> switch to the style
*
* :colo[rschema] -> list available user stylesheets (`*'-marked are loaded styles)
* :colo[rschema] {styleName} -> enable the style
* :colo[rschema]! {styleName} -> disable the style
*
* {styleName} -> the name taked away from a CSS-file-name '.css' suffix
* CSS-file are put in "~/vimperator/colors" directory
*
* `colors[chema]' command is similar to Stylish
*
* Example:
*
* auto load settings
* let g:styles = "style,name"
*
