Description: Fits response surfaces (ordinary least squares,
        generalized linear models with any family including
        quasi-families, or linear mixed-effects models) to trait data
        collected under the Geometric Framework for Nutrition and
        computes the angular separation (theta) between the nutritional
        optima of two traits, with percentile bootstrap confidence
        intervals that propagate surface-estimation uncertainty (case
        or stratified resampling; paired or unpaired). Provides a
        design-matched coverage check that simulates validation
        configurations on the user's own design and at the
        signal-to-noise ratio of the fitted surfaces, an equivalence
        test for alignment of optima, local Gaussian and mean
        curvature, and a surface-area ratio. Includes the Drosophila
        lifespan and fecundity dataset of Lee et al. (2008) "Lifespan
        and reproduction in Drosophila: new insights from nutritional
        geometry" <doi:10.1073/pnas.0710787105> as a worked example.
        The angular approach was introduced in Morimoto (2023)
        "Nutrigonometry I: using right-angle triangles to quantify
        nutritional trade-offs in performance landscapes"
        <doi:10.1086/723599>.
