 * A configuration class/dialog for KSpell.
 *
 * It contains all of the options settings.The options are set to default
 * values by the constructor and can be reset either by using the
 * public interface or by using KSpellConfig as a widget in a dialog
 * (or, preferably a tabbed dialog using KDialogBase) and letting
 * the user change the settings. This way an application that uses
 * KSpell can either rely on the default settings (in the simplest
 * case), offer a dialog to configure KSpell, or offer a dialog to
 * configure KSpell _for_this_app_only_ (in which case, the application
 * should save the settings for use next time it is run).
 * This last option might be useful in an email program, for example, where
 * people may be writing in a language different from that used for
 * writing papers in their word processor.
