Description: A complete pipeline for analysing directional data --
        headings and trajectories on the unit disk. Supply a table of
        angles directly, or reconstruct headings from movement
        trajectories imported from tracking tools ('EthoVision',
        'DeepLabCut', 'SLEAP', 'TRex', 'ANY-maze', 'TrackMate',
        'idtracker.ai', and others) via a unified dialect-based loader
        system, including multi-bodypart pose estimation with
        likelihood-weighted centroid. Derives per-trial heading
        directions using multiple rules (ring-crossing, distal point,
        pose body-axis, velocity-based, and more). Computes circular
        statistics including mean direction, resultant length, von
        Mises and wrapped Cauchy parametric fits, circular correlation
        (circular-linear and circular-circular), circular-linear
        regression (Fisher and Lee (1992) <doi:10.2307/2532334>), model
        selection among orientation models (Fitak and Johnsen (2017)
        <doi:10.1242/jeb.167056>), and uniformity and multi-sample
        hypothesis tests (Rayleigh, Watson-Williams, Hermans-Rasson
        (Landler, Ruxton and Malkemper (2019)
        <doi:10.1186/s12898-019-0246-8>), and others) with
        multiple-comparison correction. Path tortuosity follows
        Benhamou (2004) <doi:10.1016/j.jtbi.2004.03.016>. Renders
        publication-quality 'ggplot2' radial plots with overlaid rose
        diagrams, parametric density curves, non-parametric kernel
        density estimates, and circular boxplots (Buttarazzi, Pandolfo
        and Porzio (2018) <doi:10.1111/biom.12889>). Includes a
        browser-based 'shiny' graphical interface requiring no R coding
        via launch_app().
