    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 all ECL clusters loaded as Klong candidates.

            'allklm' and 'allecl' are supported/recommended)
