This is totally understandable (but would be worth pointing it out in 
the documentation of DMSwarmMigrate).

It would then be useful to have the DMSwarmSetMigrateType routine 
implemented so that I can put a PIC Swarm into MIGRATE_BASIC mode. The 
routine is mentioned in the documentation, but it seems not implemented.

Could you please add it when you have a minute?

Thanks
