nestmates spec open issues

[Brian Goetz]

John Rose proposed:
> a) Class.getnestHost() - defaults to itself if there is a resolution error

(or if there is no Nest attribute)

> b) Class.getNestMembers() -  returns full nest, fallback of self if 
> any resolution errors including it lists a nestHost that
>     does not list it.

For consistency with the classfile representation, this should probably 
omit the host class.

I would prefer that this return only the static members, which is 
consistent with the design center for reflection -- reflection over 
classfiles.
