+/**
+ * 本类是用于构建树的工具类，特点是采取lambda，以及满足指定类型的Bean进行树操作
+ * Bean需要满足三个属性：
+ * <ul>
+ *     <li>包含不为null的主键(例如id)</li>
+ *     <li>包含容许为null的关联外键(例如parentId)</li>
+ *     <li>包含自身的子集，例如类型为List的children</li>
+ * </ul>
+ * 本类的构建方法是通过{@code BeanTree.of} 进行构建，例如：
+ * <pre>{@code final BeanTree beanTree = BeanTree.of(JavaBean::getId, JavaBean::getParentId, null, JavaBean::getChildren, JavaBean::setChildren);}</pre>
+ * 得到的BeanTree实例可以调用toTree方法，将集合转换为树，例如：
+ * <pre>{@code final List<JavaBean> javaBeanTree = beanTree.toTree(originJavaBeanList);}</pre>
+ * 也可以将已有的树转换为集合，例如：
+ * <pre>{@code final List<JavaBean> javaBeanList = beanTree.flat(originJavaBeanTree);}</pre>
+ *

+ * 最后，引用一句电影经典台词： 无处安放的双手，以及无处安放的灵魂。——《Hello!树先生》
