Defines a Body associated with a location server able to give the location of one body on demand.
In case of migration, a body leaves behind it a request forwarder that allows other objects to communicate to the migrated body using the same remote reference they had before migration.
Another strategy than using a chain of forwarders is to use a server of locations that is notified of the location of the body. Upon migration, a body notifies the server of its new location. Other objects contact the server to locate a body that is not responding anymore.
