[x3d-public] Writing ANTLR4 lexer and parser for ClassicVRML

[John Carlson]

  So far, I'm not handling:
                    baseType="bboxSizeType"
                    baseType="geoSystemType"
                    baseType="loaType"
                    baseType="unitIntervalType"

But here's a non-tested grammar (minus the above and inheritance parsing,
which is critical, and extra fields on USE nodes, maybe some other things)
for review, not use in production processes.

How this compares to the VRML encoding, IDK.
