bool branchExistsRemotely();
	Check if branch exists in remote customer-repository.

    bool branchExistsLocally();
	Check if branch exists locally in customer-repository.

    bool gitPullNewBranches();
	In case the remote branch exists, but not the corresponding local one,
	then fetch the remote-branch.
