Entity Framework entity splitting

We were talking about how we can be smarter about setting up models for objects where the required fields change depending on who is looking at it - e.g. Where an administrator is setting up a user they should only need to set up email address, username, dummy password and client. When the user logs in it should then force them to fill in more details, such as name and address. One way of doing this is documented below.
