Reduce number of examples

## Context

We have been improving the examples for a while, adding lots of examples. But some examples should probably be removed.

I have seen 3 issues:

• Orphan examples that are not referenced anywhere (sometimes those should be moved to debug/
• Duplicated examples. Maybe it’s not identical, but it may not make sense to keep it anyway
• Unrecommended practices. Every example should show expected usage, not corner cases nor borderline API usage
• General style and design. I’ve seen examples with calls to alert()

As discussed today in our meeting, we will add a directory website to house VL example maps that are used in different parts of the website. major goal: keeping the versioning updated potential downfall: examples are updated only when a new version is released
