Get the tree branches as list.

        Returns:
            list: A 2d-list holding the grown branches coordinates as tupel for every age.
                Example:
                [
                [(10, 40, 90, 30)],
                [(90, 30, 100, 40), (90, 30, 300, 60)],
                [(100, 40, 120, 70), (100, 40, 150, 90), ...],
                ...
                ]
