Unclear swarm rules

[Michael Thayne]

Somehow, until recently I'd never run a fight involving swarms. Trying to do so left me with a lot of questions:

• Since swarms have no Basic Speed, where do they go in the turn sequence?
• Since swarms have no Will, do they automatically fail to resist Animal Control spells?
• When a swarm moves, who gets damaged that turn? Only people in the hex where the swarm started? Only the people in the hex where it ended? Or anyone in any hex it passes through?
• Do swarms even inflict damage on their turn, or on their victims' turn? If the latter, is it at the beginning or end of the victims' turn?
• How does running through a swarm work?
• Can a swarm "stick to" a victim that tries to run away from it? (Includes say a wizard casting levitation to escape a ground-based swarm.)

AFAICT most of these questions aren't even clear in vanilla GURPS, much less the intentionally simplified DFRPG rules. Though maybe some of them have gotten official answers in forum threads my Google-fu has failed to find?
