[x3d-public] x3d.js big, X3D4 JSON schema big, can we reduce size?

[John Carlson]

I think we can make some effort to reduce the size of the X3D JSON 
auto-generated schema (especially 4.0).  There is a lot of duplicated 
stuff there, I think.

We can look to Roy's schema for inspiration, likely.

es6x3d/x3d.js grew by an order of magnitude just by sitting there.  I 
think it's too big now.

Is there an optimizer person available?

Thanks!
