[GitHub] [arrow-datafusion] alamb opened a new issue, #3740: Add example of expr apis including simplification and coercion

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
We [programmatically make Exprs in IOx]
Also I think it would be a good time to start documenting / providing examples of working with the DataFusion Expr APIs as they are quite powerful (e.g the rewrite rules are getting quite sophisticated)
I also think writing some better examples will help improve the API / UX experience as I will
I have found several UX / improvements I will file as a part of writing this
**Describe the solution you'd like**
- [ ] A PR that moves and updates the README in the examples folder to make them more discoverable
- [ ] A PR to run examples in separate CI job, run more of them coverage
- [ ] file a ticket simplification rule for (a + const) + const vs a + (const + const)
- [ ] File ticket about needing to run the simplifier twice
**Describe alternatives you've considered**
Not document and keep all the sweet sweet tech hidden -- lol.
**Additional context**
