expose 'normals' in Wavefront object

[hananbeer]

I couldn't find how to access 'normals' in the doc. looking at the code it seems they are parsed but not exposed;

eventually I managed to access it by 'obj.parser.normals' but it isn't trivial.
also I'm not sure about the format, shouldn't they be per mesh/material, and not global?

edit:
I'm not too familiar with the format, but this seems incorrect:
obj.meshes[None].materials[0].vertices

gives an UNORDERED list of normals, not vertices, definitely not obj.vertices (which produces correct results)

It needs to be documented, but searching in the issues here you can find : #87 (comment)

I continued playing with this object a bit more and I observed the following:

edit:
ah, I see in the issue you posted, material[].vertices provides ALL information, including UV, normals, etc... kinda unclear imo.
thanks.

ok got it :)

Yep. You just have to look at the format string. The attributes are always in the same order, so its simple to check what attributes are present with a couple of "N3F" in format.
