Well, if you have only one flob of a cell, it's easy: it should be
returned. If you have more than one, all should be returned; to make
this fast&consistent, I'd use a pointered list, so that you just return
one arbitrary flob out of all the flobs of this cell, and then check if
it's the beginning of a list.

When interpolating, finding the nearest flob doesn't make that much
sense; the following algorithm makes more sense to me:
o Find flob of that cell in both this and other flobset.
o If neither is the beginning of a list, interpolate to each other.
o If one is the beginning of a list, search the flob in the list which
is nearest to the single flob and interpolate them to each other.
o If both are the beginning of lists, use some good fast algorithm to
match the nearest flobs.

Hmmm. I don't think I've really understood what you're talking about
yet... what are the two kinds of links, how should their structure
repeat and what's the problem with that?
