 * The Application class is the base class for all C++ executables

 *
 *	It determines the directory from which the running binary came,
 *	sets up the I18N catalog, the program name, and initializes
 *	an instance of the Settings class to manage all user preferences
 *	and settings.  It also manages usage tracking.
 *
 *	Applications which read experiments are derived from a subclass
 *	named DbeApplication (q.v.)
