gh-pages vs /docs for examples

[bryik]

In my own components, I typically use a /docs folder for live demos (e.g. terrain-component). This eliminates the need for a separate gh-pages branch and IMO makes publishing examples simpler.

If there is interest, I could do a PR (mostly just need to rename "examples" to "docs").
