class Foundation_API Configurable
	/// A simple interface that defines
	/// getProperty() and setProperty() methods.
	///
	/// This interface is implemented by Formatter and
	/// Channel and is used to configure arbitrary
	/// channels and formatters.
	///
	/// A property is basically a name-value pair. For
	/// simplicity, both names and values are strings.
	/// Every property controls a certain aspect of a
	/// Formatter or Channel. For example, the PatternFormatter's
	/// formatting pattern is set via a property.
	///
	/// NOTE: The following property names are use internally
	/// by the logging framework and must not be used by
	/// channels or formatters:
	///   - class
	///   - pattern (Channel)
	///   - formatter (Channel)
