    Warning:
        This function is a placeholder for Klong selections. Currently
        everything but the 'allklm' and 'allecl' lists is disabled pending study.
 
    By default, prepares the 'K_L0:allklm' list with no cuts (all KLM clusters are loaded).
    It's possible to provide the argument 'allecl' to create a list of Klong candidates built
    from all neutral ECL clusters, i.e. ECL clusters that are not matched to any track.
 
    Parameters:
        listtype (str): name of standard list options (currently only
            'allklm' and 'allecl' are supported/recommended)
