/**
 * Theme represents an application theme.
 *
 * When [[View]] renders a view file, it will check the [[View::theme|active theme]]
 * to see if there is a themed version of the view file exists. If so, the themed version will be rendered instead.
 *
 * A theme is a directory consisting of view files which are meant to replace their non-themed counterparts.
 *
 * Theme uses [[pathMap]] to achieve the view file replacement:
 *
 * 1. It first looks for a key in [[pathMap]] that is a substring of the given view file path;
 * 2. If such a key exists, the corresponding value will be used to replace the corresponding part
 *    in the view file path;
 * 3. It will then check if the updated view file exists or not. If so, that file will be used
 *    to replace the original view file.
 * 4. If Step 2 or 3 fails, the original view file will be used.
 *
 * For example, if [[pathMap]] is `['@app/views' => '@app/themes/basic']`,
 * then the themed version for a view file `@app/views/site/index.php` will be
 * `@app/themes/basic/site/index.php`.
 *
 * It is possible to map a single path to multiple paths. For example,
 *
 * ```php
 * 'pathMap' => [
 *     '@app/views' => [
 *         '@app/themes/christmas',
 *         '@app/themes/basic',
 *     ],
 * ]
 * ```
 *
 * In this case, the themed version could be either `@app/themes/christmas/site/index.php` or
 * `@app/themes/basic/site/index.php`. The former has precedence over the latter if both files exist.
 *
 * To use a theme, you should configure the [[View::theme|theme]] property of the "view" application
 * component like the following:
 *
 * ```php
 * 'view' => [
 *     'theme' => [
 *         'basePath' => '@app/themes/basic',
 *         'baseUrl' => '@web/themes/basic',
 *     ],
 * ],
 * ```
 *
 * The above configuration specifies a theme located under the "themes/basic" directory of the Web folder
 * that contains the entry script of the application. If your theme is designed to handle modules,
 * you may configure the [[pathMap]] property like described above.
 *
 * For more details and usage information on Theme, see the [guide article on theming](guide:output-theming).
 *
 * @property string $basePath The root path of this theme. All resources of this theme are located under this
 * directory.
 * @property string $baseUrl The base URL (without ending slash) for this theme. All resources of this theme
 * are considered to be under this base URL.
