User object represents a physical user of the system.
It differs from the account, as "account" represents a data structure in a target system while
"user" represents data structure in midPoint. One user typically has many accounts.
Properties of User object typically describe the user as a physical person.
Therefore the user object defines handful of properties that are commonly used to describe users
in the IDM solutions (employees, customers, partners, etc.) Custom extensions are possible by utilizing
the "extension" container.
