示例1: CombinePredicates
/// <summary>
/// Combine two predicates by trying to avoid the predicate parts of the
/// second one that are already present in the first one.
///
/// In particular, given two nodes, predicate1 and predicate2,
/// it creates a combined predicate logically equivalent to
/// predicate1 AND predicate2,
/// but it does not include any AND parts of predicate2 that are present
/// in predicate1.
/// </summary>
/// <param name="predicate1"></param>
/// <param name="predicate2"></param>
/// <param name="command"></param>
/// <returns></returns>
