/**
 * TThemeManager class
 *
 * TThemeManager manages the themes used in a Prado application.
 *
 * Themes are stored under the directory specified by the
 * {@link setBasePath BasePath} property. The themes can be accessed
 * via URL {@link setBaseUrl BaseUrl}. Each theme is represented by a subdirectory
 * and all the files under that directory. The name of a theme is the name
 * of the corresponding subdirectory.
 * By default, the base path of all themes is a directory named "themes"
 * under the directory containing the application entry script.
 * To get a theme (normally you do not need to), call {@link getTheme}.
 *
 * TThemeManager may be configured within page service tag in application
 * configuration file as follows,
 * <module id="themes" class="System.Web.UI.TThemeManager"
 *         BasePath="Application.themes" BaseUrl="/themes" />
 * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}
 * and {@link getBufferOutput BufferOutput} are configurable properties of THttpResponse.
