Description: Provides tools to perform fuzzy formal concept analysis,
        presented in Wille (1982) <doi:10.1007/978-3-642-01815-2_23>
        and in Ganter and Obiedkov (2016)
        <doi:10.1007/978-3-662-49291-8>.  It provides functions to load
        and save a formal context, extract its concept lattice and
        implications.  In addition, one can use the implications to
        compute semantic closures of fuzzy sets and, thus, build
        recommendation systems. Matrix factorization is provided by the
        GreConD+ algorithm (Belohlavek and Trneckova, 2024
        <doi:10.1109/TFUZZ.2023.3330760>).
