/**
* CThemeManager manages the themes for the Web application.
*
* A theme is a collection of view/layout files and resource files
* (e.g. css, image, js files). When a theme is active, {@link CController}
* will look for the specified view/layout under the theme folder first.
* The corresponding view/layout files will be used if the theme provides them.
* Otherwise, the default view/layout files will be used.
*
* By default, each theme is organized as a directory whose name is the theme name.
* All themes are located under the "WebRootPath/themes" directory.
*
* To activate a theme, set the {@link CWebApplication::setTheme theme} property
* to be the name of that theme.
*
* Since a self-contained theme often contains resource files that are made
* Web accessible, please make sure the view/layout files are protected from Web access.
*
* @property array $themeNames List of available theme names.
* @property string $basePath The base path for all themes. Defaults to "WebRootPath/themes".
* @property string $baseUrl The base URL for all themes. Defaults to "/WebRoot/themes".
