/**
* 循环劫;如何将摇橹劫识别为活棋.两个劫可得其一.保持二气.<br>
* 两个单子块是死棋,可以提走.如何识别为终止局面.<br>
* 本质上也是循环劫,二劫连环,与三劫连环有很大差异.<br>
* 二劫连环有三个状态: AB'<-->A'B'<-->A'B <br>
* 另一方先行: AB'<-->AB<-->A'B <br>
* 先动手的一方单方找劫材.固不是劫争.正因为两劫循环不起来,故没有"两劫循环"的说法.<br>
* * AB'-->A'B'-->A'B-->A'B-->AB<-->AB'-->AB'<br>
* (弃权致同型再现是允许的,之后不能再继续循环!) <br>
* 如果他处无棋，则按照一下循环结束.<br>
* 算法思路.局部不能两眼活棋的块相邻,作为一个整体考虑,常见的例子是双活.<br>
* 整个局部能够考虑的候选点其实很有限.<br>
