整整作了两个多小时，越写越乱，没作任何exception handling,程序混乱的一塌糊涂。凑合着看吧，排排序应该会快一些，不过已经很快乐。以后有时间再整理。

输入：
CCondition("ENG", "Red", "", "", ""),
CCondition("SWE", "", "Dog", "", ""),
CCondition("DAN", "", "", "Tea", ""),
CCondition("", "Green|White", "", "", "", CONDITION_TYPE_NEIGHBOR_LEFTATTR),
CCondition("", "Green", "", "Coffee", ""),
CCondition("", "", "Bird", "", "PaulMall"),
CCondition("", "Yellow", "", "", "DunHill"),
CCondition("", "", "", "Milk", "", CONDITION_TYPE_LOCATION, 2),
CCondition("NOR", "", "", "", "", CONDITION_TYPE_LOCATION, 0),
CCondition("", "", "Cat", "", "Mix", CONDITION_TYPE_NEIGHBOR_DIFFATTR),
CCondition("", "", "Horse", "", "DunHill", CONDITION_TYPE_NEIGHBOR_DIFFATTR),
CCondition("", "", "", "Beer", "BueMaster"),
CCondition("GER", "", "", "", "Prince"),
CCondition("NOR", "Blue", "", "", "", CONDITION_TYPE_NEIGHBOR_DIFFATTR),
CCondition("", "", "", "Water", "Mix", CONDITION_TYPE_NEIGHBOR_DIFFATTR),

输出：
*********Posibility*************0
Nation=NOR, HouseColor=Yellow, Pet=Cat, Drink=Water, Cigarette=DunHill.
Nation=DAN, HouseColor=Blue, Pet=Horse, Drink=Tea, Cigarette=Mix.
Nation=ENG, HouseColor=Red, Pet=Bird, Drink=Milk, Cigarette=PaulMall.
Nation=GER, HouseColor=Green, Pet=, Drink=Coffee, Cigarette=Prince.
Nation=SWE, HouseColor=White, Pet=Dog, Drink=Beer, Cigarette=BueMaster.

好像计算机比人聪明，竟然没用上“没有人有相同的宠物，抽相同牌子的香烟，喝相同的饮料 ”这条件，还没等我写那堆罗哩罗嗦的"unique","find"之类的东东就出唯一解了。

用了将近一天的时间才得出结果，不想已经被别人占了先。
相同的结果就不重复了。

题目我少copy过来一行，引起不少误会。这题是让拿C或C++编程。

如果要保证程序写的不太难看，而且比较容易扩展，例如随便改几个条件后程序还能算出来，就稍微费点劲了。
