Add SOAPTestingSupport ?

[Tom Zeller]

A minor detail : should I add a SOAPTestingSupport class to
opensaml-soap-api/src/test similar to SAML[12]ActionTestingSupport ?
or some other place ?

The tests for attribute queries will need to construct a SOAP
Envelope, so I was looking for one place for those few lines of code
to exist. Our SWF tests extend a Spring class, so I am unable to take
advantage of the existing OpenSAML abstract test classes.
