/**
 *   @class AxisCPPConfigDefaults
 *   @brief class for programmatically setting configuration defaults.
 *   
 *   AxisCPPConfigDefaults allows you to apply new configuration 
 *   defaults, prior to the instantiation of the first web service
 *   class in the application. These programmer-set defaults may be
 *   over-ridden by the external factors, such as..
 *    - the values in axiscpp.conf
 *    - the value of AXISCPP_DEPLOY
 * 
 *   The get/set methods don't have any effect on the ACTUAL defaults. They
 *   are simply a bundle of values which are set on the ACTUAL defaults when
 *   the apply() method is issued.
 * 
 *   It consists of...
 *   (a) get/set methods for each of the values to be found
 *       in the configuration file, namely:
 *       - ClientLog
 *       - ClientWSDDFile
 *       - XMLParserLibrary
 *       - HTTPTransportLibrary
 *       - HTTPChannelLibrary
 *       - HTTPSSLChannelLibrary 
 *       - NodeName
 *       - ListenPort
 *       - SecureInfo
 *       When the first web-services class is instantiated any values set in the config 
 *       file would over-ride those set by this class.
 *   (b) get/set methods for AxisHome 
 *       This is the programmatic equivalent of the AXISCPP_DEPLOY
 *       environment variable.
 *       When the first class is instantiated, if AXISCPP_DEPLOY is set 
 *       it will over-ride the value set by this class.
 *   (c) The apply() method takes any values that have been set on the object
 *       and set them as the Axis CPP defaults for this process. 
 * 
 *   Exceptions thrown: AxisConfigException
 * 
 *       Once the first web service is instantiated, new defaults may no longer
 *       be applied. If this is attempted an AxisConfigException is thrown.
 * 
 *   Usage examples
 *   (a) Setting the location of the axiscpp.conf file to the 
 *      "current working directory"
 * 
 *      AxisCPPDefaultConfig defConfig;
 *      defConfig.setAxisHome(".");
 *      defConfig.apply();
