[x3d-public] C++ SAI: setters and addChildren return void

[John Carlson]

This link discusses many options for C++.  If method chaining is not
preferred, how about examples with “auto “?  See link.  I don’t really know
about auto, since my C++ knowledge dates from the 90s.

I don’t mind code generation, indeed, if void is promoted in the standard,
I would be happy, because my generator and parser already work.
