/**
* Assignment processor is recomputing user assignments. It recomputes all the assignments whether they are direct
* or indirect (roles).
*
* Processor does not do the complete recompute. Only the account "existence" is recomputed. I.e. the processor determines
* what accounts should be added, deleted or kept as they are. The result is marked in account context SynchronizationPolicyDecision.
* This step does not create any deltas. It recomputes the attributes to delta set triples but does not "refine" them to deltas yet.
* It cannot create deltas as other mapping may interfere, e.g. outbound mappings. These needs to be computed before we can
* create the final deltas (because there may be mapping exclusions, interference of weak mappings, etc.)
*
* The result of assignment processor are intermediary data in the context such as LensContext.evaluatedAssignmentTriple and
* LensProjectionContext.accountConstructionDeltaSetTriple.
