/*
* Export probabilities of switches from Prolog to C. Switches is

*
* sw(Id,InstanceIds,Probs,SmoothCs,Fixed,FixedH),
*
* where
* Id: identifier of the switch
* InstanceIds: list of ids of the instances of the switch
* Probs: current probabilities assigned to the instance switches
* SmoothCs: current pseudo counts assigned to the instance switches
* Fixed: probabilities fixed?
* FixedH: pseudo counts fixed?
*
* The structures for switch instances have been allocated. This
* function only fills out the initial probabilities.
