Description: Provides a workflow for probing, plotting, and checking
    cross-level interaction effects in two-level mixed-effects models fitted
    with 'lme4' (Bates et al., 2015) <doi:10.18637/jss.v067.i01>. Implements
    simple slopes analysis following Aiken and West (1991,
    ISBN:9780761907121), Johnson-Neyman intervals following Johnson and Fay
    (1950) <doi:10.1007/BF02288864> and Bauer and Curran (2005)
    <doi:10.1207/s15327906mbr4003_5>, and grand- or group-mean centering as
    described in Enders and Tofighi (2007) <doi:10.1037/1082-989X.12.2.121>.
    Tests and intervals use Satterthwaite degrees of freedom via 'lmerTest'
    (Kuznetsova et al., 2017) <doi:10.18637/jss.v082.i13> by default, with
    Kenward-Roger and between-cluster alternatives. Also provides confidence
    and new-cluster prediction intervals for simple slopes in random-slope
    models, contour plots of predicted outcomes over the predictor-by-moderator
    space, and leave-one-cluster-out influence diagnostics for the
    interaction.
