* Module for testing SOAP WSDL web services.

* This module can be used either with frameworks or PHPBrowser.
* It tries to guess the framework is is attached to.
* If a endpoint is a full url then it uses PHPBrowser.
*
* ### Using Inside Framework
*
* Please note, that PHP SoapServer::handle method sends additional headers.
* This may trigger warning: "Cannot modify header information"
* If you use PHP SoapServer with framework, try to block call to this method in testing environment.
