Let's avoid declaring ShaderNode outside of ShaderNode.js and float, uint, etc outside of ShaderNodeElements.

Let's avoid declaring ShaderNode outside of ShaderNode.js

Why? I think it would be better not to export NodeHandler and ShaderNodeScript directly.

float, uint, etc outside of ShaderNodeElements.

I did not revert this change here (I only made a cacheMaps object from cacheMaps).

Yes, yes!! So I reopened, that part was great. :)
