[Swarm-Support] Now really close to fixing the warnings about inconsistent method declarations

[Paul Johnson]

Nevertheless, the "forward reference" to protocols to be defined later 
is supposed to work, as described in this manual:

http://www.seat-1.com/IntarS_000002_Ressources/tables/homepage/ObjectiveC/moreobjc.htm


So in defobj.h I'm trying by inserting this:

@protocol OutputStream, HDF5;

RIGHT BEFORE this:

@protocol CreatedClass <Create, DefinedClass>

As I fiddle around, that gets me really really far past the compiler 
warnings. Now I can make the method names match, such as

- (void)lispOutShallow: (id <OutputStream>)stream;

in defobj.h and the collections library.

But then this thing with moduleMap happens and I don't know what it is 
about. Do you?
