Description: Based on individual market shares of all participants in a
        market or space, the package offers a set of different
        structural and concentration measures frequently - and not so
        frequently - used in research and in practice. Measures can be
        calculated in groups or individually. The calculated measure or
        the resulting vector in table format should help practitioners
        make more informed decisions. Methods used in this package are
        from: 1.  Chang, E. J., Guerra, S. M., de Souza Penaloza, R. A.
