Title: Tidying, Analysis, and Fast Visualization of Animal and Plant
        Pedigrees

Description: Provides tools for the analysis and visualization of animal and
    plant pedigrees. Analytical methods include equivalent complete generations,
    generation intervals, effective population size (via inbreeding, coancestry,
    and demographic approaches), founder and ancestor contributions, partial
    inbreeding, genetic diversity indices, and additive (A), dominance (D), and
    epistatic (AA) relationship matrices. Core algorithms — ancestry tracing,
    topological sorting, inbreeding coefficients, and matrix construction — are
    implemented in C++ ('Rcpp', 'RcppArmadillo') and 'data.table', scaling to
    pedigrees with over one million individuals. Pedigree graphs are rendered
    via 'igraph' with support for compact full-sib family display; relationship
    matrices can be visualized as heatmaps. Supports complex mating systems,
    including selfing and pedigrees in which the same individual can appear as
    both sire and dam.
