函数说明：
指示编辑到指定方位模式现已完成。这使得该系统删除该临时数据结构，它创建以方便编辑。这个函数应该经过被称为程序已完成编辑操作的序列（除在一个面模型创建和更新）。注意，如果该例程不叫然后无妨的结果，比其它该方案将消耗更多的内存比是必要的。

函数参数：
第1个参数为输入：
model代表参数变量，tag_t 为输入参数类型，我们已完成编辑模式。

UF_FACET_model_edits_done函数实例代码演示：
这个示例程序创建一个四面体的面模型。 它然后检查模型中的边缘的邻接和凸。最后，它会从四面体一个方面，并增加了另一三个方面的顶点，其中在四面体的内部向上推使得有在所得模型三凹边。 它即可查询并打印所有模型边缘的凸度。
