这段代码实现了一个名为CGroupInfo的类的构造函数，该类用于保存给定图中的节点分组信息。构造函数传入一个指向Graph对象的shared_ptr智能指针，然后遍历图中的每个节点，当遇到kConcat节点时，将其输出的唯一名称作为键，其输入节点的唯一名称和大小信息作为值存储在m_groupMembers、m_groupMembersSize、m_groupMembersInpSize等成员变量中，当遇到kTransLayoutAfterSlice节点时也是同样的处理方式，当遇到图的输入节点时，将其唯一名称和大小信息也存储在m_groupMembers、m_groupMembersSize、m_groupMembersInpSize等成员变量中。最终，CGroupInfo对象包含了图中每个节点的分组信息。
