/// Implement this method to provide app-specific behavior when an already

/// For example, activate an existing app window or create a new app window.
/// |command_line| will be read-only. Do not keep a reference to
/// |command_line| outside of this method. Return true if the relaunch is
/// handled or false for default relaunch behavior. Default behavior will
/// create a new default styled Chrome window.
///
/// To avoid cache corruption only a single app instance is allowed to run for
/// a given CefSettings.root_cache_path value. On relaunch the app checks a
/// process singleton lock and then forwards the new launch arguments to the
/// already running app process before exiting early. Client apps should
/// therefore check the CefInitialize() return value for early exit before
/// proceeding.
///
/// This method will be called on the browser process UI thread.
