docstr: Computes Euclidean distance between atoms and a 3D point.
  
  Parameters
  ----------
  df : DataFrame
      DataFrame containing entries in the `PandasMmtf.df['ATOM']`
      or `PandasMmtf.df['HETATM']` format for the
      the distance computation to the `xyz` reference coordinates.
  xyz : tuple, default: (0.00, 0.00, 0.00)
      X, Y, and Z coordinate of the reference center for the distance
      computation.
  
  Returns
  ---------
  pandas.Series : Pandas Series object containing the Euclidean
      distance between the atoms in the record section and `xyz`.
