 * This class gives access to the OO configuration api.
 * It contains 4 get and 4 set convenience methods for getting and settings properties
 * in the configuration. <br/>
 * For the get methods, two parameters must be given: name and parent, where name is the
 * name of the property, parent is a HierarchyElement (::com::sun::star::configuration::HierarchyElement)<br/>
 * The get and set methods support hieryrchical property names like "options/gridX". <br/>
 * NOTE: not yet supported, but sometime later, 
 * If you will ommit the "parent" parameter, then the "name" parameter must be in hierarchy form from 
 * the root of the registry.
