Well, I'd like to have some way of creating a new ScDocument.  In 
looking through sc/qa/unit/ucalc.cxx, it /appears/ that all I need do is:

m_xDocShRef = new ScDocShell(
    SFXMODEL_STANDARD
  | SFXMODEL_DISABLE_EMBEDDED_SCRIPTS
  | SFXMODEL_DISABLE_DOCUMENT_RECOVERY
);

I'm clearly missing something, likely in regards to 
BootstrapFixture::setUp() and ScDLL::Init().  Help!

Thanks,

Kevin
