[x3d-public] x3dom prototypes, extern proto (J. Scheurich)

[Andreas Plesch]

The scene uncovered one more oversight, eg. not dealing quite properly
with fields without a default value in ProtoInterface, for example for
outputOnly fields.

Upon further inspection, it looks as if the empty coordIndex fields
are an interesting way to indicate to the browser to not render the
geometry, rather than just omitting the Shape. The spec. actually
seems to be quiet on this case leaving it undefined.

Also, the incorrect url seems to be a way to not want to load the
externproto, hoping to fall back on a proto with the same name loaded
earlier, in the parent scene. Rather than just not including the
externproto in this place.

I commented the Shapes with the empty geometries and the unwanted
externproto, and it looks more reasonable now, eg. no more red lines.

Since the scene looks better full screen, let me provide a standalone page:

https://andreasplesch.github.io/x3dom/test/functional/proto/extern/vrml_benz/kurve_benz_maximum.html

Sometimes pressing 'r' to reset the view helps with the animated viewpoints.
