Create a New Feature 创建NXfeature的标准过程
  w. A$ [6 `- i4 h* [5 e6 b: M9 ?1.Create an instance of the builder object for the desired feature type providing a null object as input.
* Z, [8 P& F; Y) b. `: d5 N创建一个builder实例，null作为输入
2.Edit the properties of the builder object to set the feature parameters and options.
5 F: T4 s6 O% X0 |9 S  \9 r编辑创建的builder，设置一些参数或者选项
3.Use the Commit method of the builder object to create an instance of the feature.  The Commit method will return the new feature object.
使用commit的方法来创建这个feature的实例，这样就可以返回一个feature对象
% u. W6 i% H! |1 ]4.Use the Destroy method of the builder object to delete the builder object.
+ S% C1 k, D" `3 e, X1 Y使用destory方法删除builder对象。
编辑特征也是同样的操作过程！
