/** @addtogroup Address

An address belongs to another object, determined by the ::GncOwner.
It is the owner that assigns a name and identifier to the address.
In effect, an address is just a building - to make it useful to
GnuCash, it needs to be tied to a person. After all, you cannot
invoice a building, you invoice a person working / living in the
building.

QOF needs to handle all objects generically and to tie the address
to an owner, QOF must be able to find each - as entities.

This allows QOF to follow the hierarchy of objects without having
to call any application-specific routines.

To achieve this, new GncAddress routines have been added. An address
is now created with a NULL parent and the parent set explicitly using
the QOF object declaration. Whilst this adds functionality, it is
important that a valid ::GncOwner entity is always set as a parent.
This is an API issue - QOF will always set the parent provided that
a suitable entity is passed to the qofAddressSetOwner routine. It is
up to you to pass a suitable entity.
