-// stuff I see no reason to have virtual.  but because it's impossible (w/o virtual inheritance to have dynamic fsa ff know where the impl's data starts, implemented a sync (copy) method that needs to be called.  init_name_debug was already necessary to keep state in sync between ff and ff_from_fsa, so no sync should be needed after it.  supposing all modifications were through setters, then no explicit sync call would ever be needed; updates could be mirrored.
