/**
 * Factory class for creating blank instances of the OWL Reasoner.
 * <p>
 * The reasoner can be configured using three properties (set as
 * properties of the base reasonder URI in a configuration model). These are:
 * <ul>
 * <li><b>derivationLogging</b> - if set to true this causes all derivations to
 * be recorded in an internal data structure for replay through the {@link com.hp.hpl.jena.reasoner.InfGraph#getDerivation getDerivation}
 * method. </li>
 * <li><b>traceOn</b> - if set to true this causes all rule firings and deduced triples to be
 * written out to the Logger at INFO level.</li>
 * <li><b>ruleThreshold</b> - which limits the number of rules that can be fired on a single 
 * data processing stage to the given number (useful to limit infinite runaways). </li>
 * </ul>
