Could someone please explain the difference between Tools -> Family  
Tree Repair -> Rebuild Reference Maps and Rebuild Secondary Indices.

I understand that the first calls write.py reindex_reference_map and  
the second calls rebuild_secondary. I can see that  
reindex_reference_map rebuilds the reference maps by going through  
each primary object, and calling update_reference_map, but what  
exactly does rebuild_secondary do?

Also, in write.py I have had to call self.__connect_secondary() and  
self.__open_undodb() before doing the gramps_upgrade_16. Would I have  
to do that if I used the reindex_reference_map function?
