自动生成类名头文件，自动生成类名头,该Python脚本程序的

该Python脚本程序的功能是在./inc/目录下自动生成类头文件包含文件。

在大工程中，有很多类实义在不同层次的头文件中，在需要引用的时候则到包含它们，如需要使用自定义的TobBar,StatusBar,StateMachine类：

include "widget/bar/topbar.h"

include "widget/bar/statusbar.h"

include "stateManager/statemachine.h"

...

引用者不仅要知道类的名称还要知道类定义的文件所在的路径。很麻烦，如果可以如下包含就好了：

include "TopBar"

include "StatusBar"

include "StateMachine"

直接引用类名，不用关心头文件名称与所在路径。

实现方法是，在./inc/目录下以类名生成包含文件，在包含文件中加入类所在的头文件。如TopBar，在./inc/下创建TopBar文件，TopBar文件内容为：

include ".././widget/bar/topbar.h"

这个脚本程序就是遍历当前目录下的所有头文件，查找出每个头文件中定义的类名，并在./inc/目录以类名创建包含文件。
