ElevatorExponentialProfile example

[narmstro2020]

There seems to be an example not linked to the docs website in the code base. Exponential Elevator Profile and one for simulation as well.

When looking at the code there doesn't seem to be a correct Feedforward. SimpleMotorFeed forward is used instead.

Question #1: Is this correct or an oversight?

Question #2: Can ExponentialProfile be used with systems like Arms and Elevators as is or would they require modification to be more accurate as currently they take in kV and kA?

The examples need an overhaul in general. There's way too many to maintain, most of them are bad or outdated, and they're rarely used because teams don't know they exist.

We should replace all the elevator-adjacent examples with just one. Small "how do I use this feature" examples should probably be moved to the API docs, or frc-docs (the former is more likely to be kept up to date).

Either trapezoid or exponential profiles can be used, though they don't reflect the true dynamic limits. It works as long as the profile is conservative enough.
