Stubble script

[Ravi Pandya <ravi>]

I need a modification to the current stubble script so that I can have
"deferred proxy" classes -- classes that define proxy methods but
cannot themselves have proxies. (The particular example is Doc, which
defines proxy methods for accessing its contents, but noone should
ever have a DocProxy; they might have a TextDocProxy or a
LinkDocProxy). I think we just need another keyword such as
"DEFERRED_PROXY" that declares a bunch of methods proxies but doesn't
generate a proxy class.
