docs: def get_relative_from_paths(self, filepath, paths):
          """
          Find the relative filepath from the most relevant multiple paths.
  
          This is somewhat like a ``os.path.relpath(path[, start])`` but where
          ``start`` is a list. The most relevant item from ``paths`` will be used
          to apply the relative transform.
  
          Args:
              filepath (str): Path to transform to relative.
              paths (list): List of absolute paths to use to find and remove the
                  start path from ``filepath`` argument. If there is multiple
                  path starting with the same directories, the biggest will
                  match.
  
          Raises:
              boussole.exception.FinderException: If no ``filepath`` start could
              be finded.
  
          Returns:
              str: Relative filepath where the start coming from ``paths`` is
                  removed.
