Synopsis [Computes actual reference counters.]
Description [Stores all the nodes used in the mapping in the array pMan->vMapping.
The nodes are stored in the random order.]
Description [Collects the nodes used in the mapping in array pMan->vMapping.
Nodes are collected in reverse topological order to facilitate the
computation of required times.]
