Description: Fault tree analysis with tidy data. Represent a fault tree
        as two tables, one of nodes (the top event, gates and basic
        events) and one of edges, so the whole workflow stays in
        ordinary data frames. Derive the Boolean equation of the top
        event, enumerate the truth table, and find minimal cut sets
        with the Method of Obtaining Cut Sets (MOCUS) algorithm of
        Fussell and Vesely (1972), implemented in 'R' and, by default,
        in C++ through 'Rcpp'. Evaluate thousands of binary or
        probabilistic scenarios in one vectorized call, put uncertainty
        intervals around the top-event probability, follow it over
        time, and rank which component fix lowers it most. Lay out and
        draw the tree with 'tidygraph', 'igraph' and 'ggplot2'. Methods
        follow the "Fault Tree Handbook" of Vesely, Goldberg, Roberts
        and Haasl (1981)

        port with the same functions ships in the same repository.
