[MOAB-dev] MOAB insights?

[Nico Schlömer]

Absolutely!

I'm interested to see
 * how I/O works,
 * how edges/faces arecreated,
 * how relationships are queried (Which cells does this face border on?
Which nodes does this cell have? etc)

If there's an example in the sources, I'd be more than happy to look at
that, too, of course.

Cheers,
Nico
