Importing NexusObject from nexus3d in a js file

[rvouilloz]

Hello,
Thank you very much for this very interesting development.
I would like to integrate a nxz to a three.js environment. But I'm not sure how to declare the import of your library.
I installed three and then nexus3d via npm. In your example, you use a NexusObject. What declaration should I use to import it into my file?
I tried import { NexusObject } from 'nexus3D'; but it doesn't seem to work.
Thanks
