I landed on this library docs when trying to learn what quarterions are for. Although the library has a vast documentation it doesn't explain what quaternions are and why they are used. When I was tau…

Improvements:
- no duplicate factorisations (ramified_primes)
- doc correctly states that ramified_primes is implemented over number fields
- add ramified_infinite_places
- is_division_algebra over …

This will allow us to support _all_ OpenSim joint types in Moco (e.g., `BallJoint`, `ScapulothoracicJoint`, etc).
We can implement this by incorporating the linear transform matrix, `N`, for kinema…
