In general all accessing of internal OSPF state should be performed
through the OSPF class, although this principle is violated in a few
places in xrl_target.cc.

OSPF partitions its world into areas, the name of the class happens to
be AreaRouter, this does not imply that the router is an area border router.

Provide the area ID for the area that you are interested in, if you are
adding an interface that requires an area ID then provide it as an
argument to the XRL.

The PeerManager class has a method "get_area_list" that will provide a
list of all the configured areas.
