 * This deployer is called directly by the VFS Deployment Framework, as the Input object
 * for this is a Configuration class.
 * 
 * In regular flow, {@code HornetQConfigParserDeployer} will have parse HornetQ XML configuration files and created {@code Configuration} outputs.
 * <br>
 * In an alternate flow, other deployers (e.g. TorqueBox) may instantiate a Configuration object directly and this deployer will take over after.
 * <p>
 * The <strong>only resources deployed by this deployer</strong> are:
 * <ul>
 *   <li>core queues ({@link Configuration#getQueueConfigurations()}</li> 
 *   <li>address settings ({@link Configuration#getAddressesSettings()}</li> 
 *   <li>security roles ({@link Configuration#getSecurityRoles()}</li> 
 * </ul>
 * Other attributes of the Configuration are not deployed by these deployers.
