	/// The Debugger class provides an interface to the debugger.
	/// The presence of a debugger can be checked for,
	/// messages can be written to the debugger's log window
	/// and a break into the debugger can be enforced.
	/// The methods only work if the program is compiled
	/// in debug mode (the macro _DEBUG is defined).
