/**
 * TSoapService class
 *
 * TSoapService processes SOAP requests for a PRADO application.
 * TSoapService requires PHP SOAP extension to be loaded.
 *
 * TSoapService manages a set of SOAP providers. Each SOAP provider
 * is a class that implements a set of SOAP methods which are exposed
 * to SOAP clients for remote invocation. TSoapService generates WSDL
 * automatically for the SOAP providers by default.
 *
 * To use TSoapService, configure it in the application specification like following:
 * <code>
 *   <services>
 *     <service id="soap" class="Prado\Web\Services\TSoapService">
 *       <soap id="stockquote" provider="MyStockQuote" />
 *     </service>
 *   </services>
 * </code>
 * PHP configuration style:
 * <code>
 *  'services' => array(
 *    'soap' => array(
 *     'class' => 'Prado\Web\Services\TSoapService'
 *     'properties' => array(
 *       'provider' => 'MyStockQuote'
 *	   )
 *    )
 *  )
 * </code>
 *
 * The WSDL for the provider class "MyStockQuote" is generated based on special
 * comment tags in the class. In particular, if a class method's comment
 * contains the keyword "@soapmethod", it is considered to be a SOAP method
 * and will be exposed to SOAP clients. For example,
 * <code>
 *   class MyStockQuote {
 *      / **
 *       * @param string $symbol the stock symbol
 *       * @return float the stock price
 *       * @soapmethod
 *       * /
 *      public function getQuote($symbol) {...}
 *   }
 * </code>
 *
 * With the above SOAP provider, a typical SOAP client may call the method "getQuote"
 * remotely like the following:
 * <code>
 *   $client=new SoapClient("http://hostname/path/to/index.php?soap=stockquote.wsdl");
 *   echo $client->getQuote("ibm");
 * </code>
 *
 * Each <soap> element in the application specification actually configures
 * the properties of a SOAP server which defaults to {@link TSoapServer}.
 * Therefore, any writable property of {@link TSoapServer} may appear as an attribute
 * in the <soap> element. For example, the "provider" attribute refers to
 * the {@link TSoapServer::setProvider Provider} property of {@link TSoapServer}.
 * The following configuration specifies that the SOAP server is persistent within
 * the user session (that means a MyStockQuote object will be stored in session)
 * <code>
 *   <services>
 *     <service id="soap" class="Prado\Web\Services\TSoapService">
 *       <soap id="stockquote" provider="MyStockQuote" SessionPersistent="true" />
 *     </service>
 *   </services>
 * </code>
 *
 * You may also use your own SOAP server class by specifying the "class" attribute of <soap>.
