Changed gui wording in lib and app to view wording, since MVC views do not necessarily deal with GUIs. And moved files
so structure is similar in lib and app.
We decided to stop code reviews for now, because they are too time consuming. We will consider reintroducing them when
the project is at a more mature stage.
This change adds the commit message template in file
.git_commit_message.txt. It will be used after once running:
$ git config commit.template .git_commit_message.txt
