Added Lines Segments Example

[eduardfossas]

Description

Hello, I don't know how useful this will be to anyone, but I was doing some generative art the other day and I put together a few lines of code trying to use LineSegments and I realised there were no examples in the Three.js documentation site, so I decided to create one.

Let me know if you want me to change something or contribute in another way.

Warm regards.

Thanks for filing the PR. But since there are already multiple examples using LineSegments, it would better to share your code in the forum under the resources category.

Existing examples that could be added to the doc page of LineSegments are:

https://threejs.org/examples/webgl_buffergeometry_drawrange
https://threejs.org/examples/webgl_buffergeometry_lines_indexed
https://threejs.org/examples/webgl_buffergeometry_selective_draw

It would be great if you could add them with a new PR.

Hello @Mugen87. That was exactly my point! If I went to the LineSegments documentation page I could not find any examples, so I am happy to do a new PR adding the examples that you shared.

Thank you!
