Description:
 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. """
