Description: Reduces compact letter displays (CLDs) of all pairwise
        comparisons. A CLD gives two groups a common letter exactly
        when they are not significantly different. The package finds a
        display with the fewest letter assignments that keeps every one
        of these relationships. This is the assignment-minimum clique
        covering problem of Ennis, Fayle, and Ennis (2012)
        <doi:10.1145/2133803.2275596>, solved as a mixed-integer linear
        program with 'HiGHS'. Among the displays with the fewest
        assignments, it returns one fixed canonical display, so the
        result does not depend on the solver. The package includes the
        wheat yield example of Piepho (2004)
        <doi:10.1198/1061860043515>.
