[Rd] initialization of S4 classes/methods

I'm seeing weird issues in methods initialization, i.e. loading
marrayClasses loads Biobase, and when explicitly done, as in

   library(Biobase)
   library(marrayClasses) 

is fine, but when Biobase is loaded via a require statement in
marrayClasses' .First.Lib, I end up with:

  Warning message: In the method signature for function "coerce", class
  "exprSet" has no current definition in: matchSignature(signature,
  fdef, where) 

and based on the "band-aid" working above, suggests an initialization
or evaluation timing problem.

(and exprSet is defined in the Biobase package).

best,
-tony
