Green.AgileMapper项目-新增DO和DTO代码生成
如果你还不了解Green.AgileMapper的用意，作用请先一步到上篇Green.AgileMapper开源项目的使用，如果你觉得运行时（Runtime）的Mapper效率存在问题，在这个版本中有了更新，新增了C#直接代码的生成，这里的生成都已3.0后的扩展方法实现，你可以很方便的一句代码实现两者的转化。
代码生成我本想利用T4模板，但是由于我们的项目IDE版本是VS2008，对于T4的参数传递支持还不是很友好，你可能说用AppDomain.SetData,或者CallContext.LogicalSetData，但是可惜我们的饿MappingRule是不可序列化的，所以最后我只得采用了字符串拼接最笨的办法，为了应对生成策略不同，在这里我们加入了策略模式来应付，来看看代码结构吧：
在这里只支持对do的二级属性映射为dto的平面属性，全部针对IMappingRule生成代码，在这里为了生成合法的代码而非表达式，对以前的表达式进行了重新的标准约定，在代码注释。以及对上个版本的List转换进行了多次重载，主要为了满足DTo到DO对象的特殊要求，因为我们在领域开发存储DTO的时候都是需要先取出DO对象在根据DTO在DO对象的基础上进行修改，以便ORM领域框架或者UOW的跟踪记录。
下面看看任然是上个测试类模型的代码生成（在这里测试DO，DTO类进行了重构为了更全面的测试，具体请看CodePlex http://agilemapper.codeplex.com/代码）：

在这里的代码生产后很乱并未格式化处理，需要我们在VS中自动Ctrl+K+D格式，如果你希望生成时候就帮助格式化了的话，你可以参见工具CoolFormat源代码格式化，安装工具利用CMD命令批量格式化（可以参见百度百科：http://baike.baidu.com/view/4367725.htm）。在项目暂不会考虑这块，如果你有兴趣的可以先帮助完成，谢谢。
具体请参见项目，存在任何问题或者bug可以随时给我留言，谢谢。
