    Expect a single non growth-associated maintenance reaction.

    The Non-Growth Associated Maintenance reaction (NGAM) is an
    ATP-hydrolysis reaction added to metabolic models to represent energy
    expenses that the cell invests in continuous processes independent of
    the growth rate. Memote tries to infer this reaction from a list of
    buzzwords, and the stoichiometry and components of a simple ATP-hydrolysis
    reaction.

    Implementation:
    From the list of all reactions that convert ATP to ADP select the reactions
    that match the irreversible reaction "ATP + H2O -> ADP + HO4P + H+",
    whose metabolites are situated within the main model compartment.
    The main model compartment is assumed to be the cytosol, yet, if that
    cannot be identified, it is assumed to be the compartment with the most
    metabolites. The resulting list of reactions is then filtered further by
    attempting to match the reaction name with any of the following buzzwords
    ('maintenance', 'atpm', 'requirement', 'ngam', 'non-growth', 'associated').
    If this is possible only the filtered reactions are returned, if not the
    list is returned as is.
