//! User registry in a vault is done via the metadata store
//! 
//! In addition to that the `lockchain-core ` provides some simple
//! utilities to manage Users and UserStore objects, mapping them
//! onto metadata stores.
//! 
//! In this example we will define a function that takes a generic
//! Vault implementation backend (because lockchain-core doesn't
//! provide a concrete way of doing this) and registering a user 
//! into it.
//! 
//! Please note you can't actually _run_ this code example, because
//! no concrete type can be known. The exact same example (with a type)
//! can however be found in `lockchain-files`
