Examples
   
    ?- tent_set(X, 27), var_get_violations(X, V).
    X = X{27 -> 0}
    V = 0
    Yes (0.00s cpu)

    ?- tent_set(X, 27), var_inc_violations(X, 3), var_get_violations(X, V).
    X = X{27 -> 3}
    V = 3
    Yes (0.00s cpu)

    ?- var_get_violations(a, V).
    V = 0
    Yes (0.00s cpu)

    ?- var_get_violations(_, V).
