[x3d-public] jupyter notebook

[Andreas Plesch]

Hi John, group,

I tried image textures and inlines with x3dom on jupyterlab:
https://mybinder.org/v2/gh/andreasplesch/conda/master/?urlpath=lab/tree/sphere.ipynb

Run all cells.

Here are some observations and a suggestion:

- inline works. But jupyterlab serves local files from a folder above
the folder where the notebook and resources are stored and so the
relative url to the inline starts with "./files/"
- generated X3D with ImageTexture used within an Inline works. Here
the url to the image is relative to the inline url, and so does not
need the "./files/" prefix
- x3dom has a problem with generated X3D outside of an Inline because
the serialized XML output uses self-closing tags such as <Material />
which is not HTML compatible.

So the suggestion would be to provide a method, say
x3d.toStringX3DClosingTags(), which generates explicit closing tags:
<Material></Material>

-Andreas
