TODO: Potentiall combine useAllUsers and useUser by delaying the get all users functinality
Unsure how this could work but still be clear and functional. Perhaps by passing arguments to the useUsers function
to control whether the object is substantiated... but some of the others rely on it being substantiated...Will come back to this.
