 * Homepage generator class.
 *
 * This class generates the homepage for each language defined in the configuration.
 * It creates a new index page for each language, collects all pages of that language,
 * sorts them, and sets the necessary variables for the homepage.
 * It also handles the case where the homepage already exists by cloning it.
 * Additionally, it sets the default "main" menu and adds an alias redirection
 * from the root directory if the language prefix is enabled for the default language.
