I think the best practice is to create a project with a static library target. Other developers can include it as a subproject in their projects.
As far as I know you should create a new project and that project to any other project you want use library in. Then link the projects and you can access it. The other way which I have done also, copy the library classes directly to the new project and access the library through importing the needed classes.
In my case I found creating a project and linking it with the new project is the easiest. Although copying the classes isnwhat we all do when using external libraries such as cocos2d. As far as sharing it with others, just upload it to github another place of your choice so it can be used by other dev's.
I hope this helps you.t.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
