implements IReaderListener, IWriterListener

Answers the questions by looking up the values in a Properties object. The question names match the property field names. If no answer is found in the Property object, or if the value is invalid, then the default is taken.

For the GaussianInputWriter the properties file might look like:

 Basis=6-31g
 Method=b3lyp
 Command=geometry optimization
