[x3d-public] ProtoInstance USE without name

[John Carlson]

I don't have any .x3d HTML examples for Holger's library. I can provide
json examples, if needed.  I

If you've got X3DJSONLD installed, running x_ite.sh in
X3DJSONLD/src/main/shell should look in ../Library (Holger's library copy)
and produce a plethora of .json files. I would uncomment the commented out
"exit" in several.sh to stop running all the example code generated.

But it may be easier to provide you with my copy of Holger's Library.

Thanks!

John
