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>.
