/// <summary> This class provides a simple common abstraction of a facility that logs
/// and/or displays messages or simple strings. The underlying facility can be
/// a terminal, text file, text area in a GUI display, dialog boxes in a GUI
/// display, etc., or a combination of those.
///
/// <>Messages are short strings (a couple of lines) that indicate some state
/// of the program, and that have a severity code associated with them (see
/// below). Simple strings is text (can be long) that has no severity code
/// associated with it. Typical use of simple strings is to display help
/// texts.</p>
///
/// <p>Each message has a severity code, which can be one of the following:
/// LOG, INFO, WARNING, ERROR. Each implementation should treat each severity
/// code in a way which corresponds to the type of diplay used.</p>
///
/// <p>Messages are printed via the 'printmsg()' method. Simple strings are
/// printed via the 'print()', 'println()' and 'flush()' methods, each simple
/// string is considered to be terminated once the 'flush()' method has been
/// called. The 'printmsg()' method should never be called before a previous
/// simple string has been terminated.</p>

/// has been reached and should be given as feedback to the user.

/// wrong and probably that execution has ended. They should be definetely
