 *
 *             - Using a new class LogPass as a data member, rather than
 *               using two data members, log, and pass.
 *
 *             - Changed all methods that directly access the log and pass
 *               so they access the LogPass methods.
 *
 *             - These changes will help make the Security class to be
 *               able to use multiple login and pass accounts.
 *
 *
 *  ===========================================================================
 *
 *  Remark:
 *
 *  This is the definition of the Security class. The class porvides a system
 *  to control access to certain methods in the program. It can also change 
 *  the access as well. The actual login and password are stored in a seperate
 *  class, LogPass, as a private data member of the Security class. The only
 *  methods that have access to retrieve the login and password are private.
 *  Together with the LogPass class, this Security system uses very strong
 *  encapsulation.
 *
 *  Just so you don't get the wrong idea, the is _NO_ crypto stuff here, I am
 *  no genius. This class provides an engine for retrieving the password from
 *  the user, and verification methods. But it doesn't mean you can't use this
 *  class and write your own encryption engine, or use an existing one along
 *  with this class.
