VS
  A varset
Vars
  A list of tentative variables (output)

## Description

### Modes and Determinism

- vs_all_violated(+, -) is det

## Examples

        ?- Vars=[A,B,C], tent_set(Vars, [1,2,3]), vs_create(Vars, VS),
           var_inc_violations(B, 1), vs_all_violated(VS, VSVars).
        Vars = [A{1 -> 0}, B{2 -> 1}, C{3 -> 0}]
        VS = ...
        VSVars = [B{2 -> 1}]
