Now we can just do console.log(THREE.VERSION). Thanks for the suggestiong @chandlerprall!

Using comments, though I wonder if using "rubric" thing is the right way to organize.

For the moment, the simplest way seems to be overriding theme CSS with a custom CSS file (created by copying the original theme CSS and extending it with new rules).

Feel free to improve the style. All customizations are at the end of `static/nature.css`.

Some broken stuff... :/

primitive input array offset can have a shared
value. The loader assumed inputs.length as an
index. Changed the loader to use a max offset
value. An example of shared offsets is the input
semantic TEXTANGENT and TEXBINORMAL sharing offset
values. 

Keeping the old IcosahadrenGeometry and OctahedronGeometry to double check results later.
