Yes, indeed, all the code above was generated automatically by Scheran, and
by God it works!  Interpreted backend frobbing!

The stuff above is uglier than it will be (Paul just defined some lightweight
objects that will fit nicely, and Scheran'll learn to resolve overloading and
handle casts more gracefully).  But this is the first time the backend's
actually conversed with Montage!  (Isn't it?  Rick, did you have this working
this summer?)

This test was translated from the following code from fbtestt.cxx:

void ShutdownTester::shutdownTest (ostream& oo){
        SPTR(KeyMaster) km;
        SPTR(ID) iDOfClubNamesDoc;
        SPTR(IndexedWaldo) clubNames;
        SPTR(ID) adminID;
        SPTR(BooLock) booLock;
        SPTR(Adminer) adminer;
        
        km = this->keyMaster();
        iDOfClubNamesDoc = km->fetchHomeDocID();
        clubNames = CAST(IndexedWaldo,km->fetchWaldo(iDOfClubNamesDoc, ::key("Map"), FALSE));
        adminID = CAST(ID,clubNames->get(::packOBits ("System Admin")));
        booLock = CAST(BooLock,km->login(adminID));
        adminer = booLock->boo()->fetchAdminer();
        adminer->shutDown();
        return;
}

Next week:  smarter Scheran, local models, just generally tons of fun!
