Find the Git repository if the path to open is contained inside.

In some environments it's more convenient to open a path inside a Git repository. e.g. Dragging the .xcodeproj package from Project navigator (Cmd-1) in Xcode to the Dock icon of GitUp.

Currently in this case, GitUp simply conveys the error: "could not find repository from…". I'm expecting an improvement by finding a Git repository from parent paths and prompting the user about possible match. Here's an example of UI:

I looked up in libgit2 and found the fit API: git_repository_discover. I tried some code change in initWithExistingLocalRepository in GCRepository and saw some effect.

To make UI following the path change (from received path to the Git repository), however, code changes should take place in Document (NSDocument). However, the application layer seems unable to access libgit2 directly. I wonder if I must also write APIs in GitUpKit/Core (to access that API in libgit2). e.g. create a class GCPathXxxxer and put methods therein.
