Description: Estimates structural equation models by case-based least
        squares: the latent scores of every observation are treated as
        free variables of a constrained optimization problem, so that
        arbitrary nonlinear model equations, bounds and constraints on
        latent variables and inequality constraints on parameters
        become possible.  Model equations are specified as plain text
        (e.g. "y == a*exp(b*eta)"). Gradients are obtained by automatic
        differentiation via 'RTMB', and the constrained problem is
        solved with 'nloptr' (SLSQP or augmented Lagrangian).  Missing
        data are handled case-wise.  The methodology is described in
        Oldenburg (2024) <doi:10.19139/soic-2310-5070-1868> and
        Oldenburg (2025) <doi:10.19139/soic-2310-5070-2324>.
