Base-class for variable implementations.
Implements variable implementation for variable implementation configuration of type VIC.
Subscribe propagator p with propagation condition pc.
In case schedule is false, the propagator is just subscribed but not scheduled for execution (this must be used when creating subscriptions during propagation).
In case the variable is assigned (that is, assigned is true), the subscribing propagator is scheduled for execution. Otherwise, the propagator subscribes and is scheduled for execution with modification event me provided that pc is different from PC_GEN_ASSIGNED.

Indices of subscribed actors.
The entries from base[0] to base[idx[pc_max]] are propagators, where the entries between base[idx[pc-1]] and base[idx[pc]] are the propagators that have subscribed with propagation condition pc.
The entries between base[idx[pc_max]] and base[idx[pc_max+1]] are the advisors subscribed to the variable implementation.
