BM.AE中的命令工具体系
ArcEngine本身已经有了一套很完善的命令好工具体系，但我们直接使用时还是有些困难的。
1.ICommand接口中的图片的格式是我们不常见的，我们在设置时很不好设置。
2.Engine中的Command无法替换UI，Engine中的Command已经是和UI绑定到一起的了，如果我们要放到别的UI上需要做一些转换工作。
3.IComamnd里面的一些属性都是自读的，我们继承起来很不方面，而且有些属性例如标题、图标等，是可以允许在外部设置的。
新的命令工具框架如下：
这种结构我们在设置一些属性的时候会更加灵活，最主要的是我们把Engine中的Command和UI解耦了，当我们定义好Commad和Tool之后，我们定义的Command和Tool可以在不同的UI上体现。这样就可以很好的满足我们的项目需求。而且这样我们写代码时也就比较方便，例如我的主界面的后台代码如下：
