一、题目
个人(Person)与团队(Team)可以形成一个组织(Organization)：组织有两种：个人组织和团队组织，多个个人可以组合成一个团队，不同的个人与团队可以组合成一个更大的团队。
使用控制台或者JavaFx界面完成以下功能：维护团队，并递归显示团队的所以成员。
控制台客户端功能提示：简化起见，采用自顶向下的方式创建团队，例如，创建“t1”团队，然后创建“t1”的子团队“t1.1”团队、“t1.2”团队，创建“t1.1”的子团队“t1.1.1”，子团队“t1.1.1”由“p1”、“p2”和“p3”三个人。创建完成后，递归输出这些对象；例如，当前情况下输出这样的消息：
团队t1有t1.1, t1.2, t1.3三个子对象；团队t1.1有t1.1.1一个子对象；团队t1.1.1有p1, p2, p3三个子对象。
在此基础上修改一个对象，例如，把p3对象从子团队“t1.1.1”中删除，然后添加到t1.1团队中；完成这些操作后，递归输出这些对象，结果应该是
团队t1有t1.1, t1.2, t1.3三个子对象；团队t1.1有p3, t1.1.1两个子对象；团队t1.1.1有p1, p2两个子对象。
JavaFx界面提示：JavaFx的基本界面如下，同学们在此基础上适当修改.
左边是创建对象的树状结构展示，右边是选中某一个节点后的操作。例如，如果选中T12。然后就可以输入T121，输入后直接刷新树状结构。
