如何新增一个FactAnalyzer？

实现一个类，名称形式如下XXFactAnalyzer，该类需继承AbstractFactAnalyzer，并添加注解FactAnalyzerAnnotations；
为上述类无参构造函数；
可以添加static 属性保存该FactAnalyzer分析的相关结果；
实现public void prepare(Object object) {}、public void analysis(Object object, Collection factChain) throws FactAnalyzerException {}、public String getName() {}、public String getType() {}、public String getFactDescription() {}以及public String toString() {}方法。
prepare方法做一些前置条件的筛选，并根据筛选结果判断是否启用该FactAnalyzer（所有新增FactAnalyzer默认启用）；
analysis方法完成具体的事实分析。
