/**
 * TAssetManager class
 *
 * TAssetManager provides a scheme to allow web clients visiting
 * private files that are normally web-inaccessible.
 *
 * TAssetManager will copy the file to be published into a web-accessible
 * directory. The default base directory for storing the file is "assets", which
 * should be under the application directory. This can be changed by setting
 * the {@link setBasePath BasePath} property together with the
 * {@link setBaseUrl BaseUrl} property that refers to the URL for accessing the base path.
 *
 * By default, TAssetManager will not publish a file or directory if it already
 * exists in the publishing directory and has an older modification time.
 * If the application mode is set as 'Performance', the modification time check
 * will be skipped. You can explicitly require a modification time check
 * with the function {@link publishFilePath}. This is usually
 * very useful during development.
 *
 * TAssetManager may be configured in application configuration file as follows,
 * <code>
 * <module id="asset" BasePath="Application.assets" BaseUrl="/assets" />
 * </code>
 * where {@link getBasePath BasePath} and {@link getBaseUrl BaseUrl} are
 * configurable properties of TAssetManager. Make sure that BasePath is a namespace
 * pointing to a valid directory writable by the Web server process.
