Removal of users
Removal of users is a function that I'm missing. It is a feature that prevents davical from really good use. It prevents removing old users that has fallen out of time. By users in this case I'm referring to system users regardless of user role.
This feature is also important while setting up and understanding the basic semantics behind davical. This since you will need to laborate with and maybe not wanting to rename or wiping the database just because you added some users to many.
Now I understand that deletion is a delicate thing, you wouldn't want any user to be able to do removal of users since it can mess things up really good.
