Creation of the synchronization element list.

To generate synchronization information, it is assumed that the owner() of each entity is correct.

Based on the communication file, constructs the structures for synchronization. It is a list of elements, each element consisting of the processor rank with which communication must occur and the localId() of the mesh entities that must be sent and received.

If the group associated with this instance is allItems(), it is checked that all entities in the family are either domain-local or ghosts. If an entity is not in this case, it will not be synchronized and parallelism consistency will not be ensured: this is a fatal error.

Operation on any group (other than allItems) is primarily dependent on changeLocalIds() being implemented on all groups.
