Description: Fits non-crossing regression quantiles as a function of
        linear covariates and multiple smooth terms, including varying
        coefficients, via B-splines with L1-norm difference penalties.
        Random intercepts and variable selection are allowed via the
        lasso penalties. The smoothing parameters are estimated as part
        of the model fitting, see Muggeo and others (2021)
        <doi:10.1177/1471082X20929802>. Monotonicity and concavity
        constraints on the fitted curves are allowed, see Muggeo and
        others (2013) <doi:10.1007/s10651-012-0232-1>, and also
        <doi:10.13140/RG.2.2.12924.85122> or
        <doi:10.13140/RG.2.2.29306.21445> some code examples.
