+--quoggles.auxboxes.booleanop.BooleanOp_Box
Input: two Boolean values
Output: a Boolean that is the result of applying an operation
on the two input Boolean values (specified via a parameter).
No implicit conversions are applied to the input. If one of the inputs is
null, the output is null.

public void execute()
throws QueryExecutionException
BoxInputNotSetException if the inputSet
flag indicates the no input has been set for this box.
May throw other QueryExecutionExceptions.
The implementation of this abstract sets the output to be equal to the
input.

throws InvalidInputException
Boxsuper.setInputs(inputs)) so that consistency checks are
done and some flags are correctly set.

BoxDefaultBoxRepresentation.
If your subclass has any parameters, you will probably have to design
your own representation and override this method for example as follows:
if (iBoxGRep == null || !(iBoxGRep instanceof MYOWNBOX_Rep)) {
iBoxGRep = new MYOWNBOX_Rep(this);
}
return iBoxGRep;
