* Parameter subclass for the boolean type. Most of the
* functionality is already implemented in {@code Parameter},
* leaving only construction and type definition to the
* subclasses.
* <br><br>
* This class contains three constructors, two of which are public.
* One assumes the parameter is not critical and only takes a name
* and initial value, while the other allows the critical flag
* to be set as well. The third constructor is protected and allows
* the monitor flag to be set as well, allowing subclasses of this class
* to be used as monitors. See {@link BooleanMonitor} for an example
* of this usage.
* <br><br>
* The validate method is overridden here and left blank since not all
* parameters actually require validation, but where validation is
* required this method can be anonymously overridden on an instance-to-instance
* basis.
