由Podfile组建的工程里，每一个模块都有一个对应的PodSpec文件，在Pods/Headers中，每一个Pods的Header都有Public和Private之分。清楚的知道哪些文件是公开还是私有，对未来模块化框架下开发有很多作用。
这次脚本使用Python开发，顺便学习下。
思路：
1、遍历所有Pods中的文件以及文件的import，获得一个大的字典。如：
{pod1:{file1:file1node,file2:file2node}}
pod1是pod名字，file1是文件名，file1node是一个包含多个信息的文件实例。
2、递归遍历每个文件和文件里的import，如果检测到import的文件不是当前pods，标记为公开。（在一个Pods中，递归过的文件标记为已递归不再递归，加快速度）
3、扫描字典，把标记为公开的文件放在数组里，提供结果。
4、把结果分别写进各个pod的podspec中：s.public_header_files = xxx。podspec是ruby格式的。可以把结果写在另一个文件里。
