Okay, I'll give this a bump by asking some more specific questions. After 
slogging through some of the basics of using the ArangoJS driver, I've been 
able to construct a basic genealogy tree. But I'm still struggling 
especially with edges.

Let's just take it piece by piece.

What, for example, is the difference between a graphedgecollection and just 
an edgecollection?
