Description: Thread-safe C++ trust region optimizers, each exposed both
        as an R function and as a C-callable entry point (with function
        pointers registered for other packages to call without linking
        against this package's shared library) so they can be used from
        parallel C++ code such as in 'nlmixr2est'. Includes a port of
        the two-derivative trust region algorithm in the 'trust'
        package by Charles J. Geyer; a port of the Steihaug truncated
        conjugate-gradient trust region method from the 'basin' Rust
        crate (Steihaug (1983) <doi:10.1137/0720042>); and ports of M.
        J. D. Powell's derivative-free BOBYQA (Powell (2009), Report
        DAMTP 2009/NA06) and NEWUOA (Powell (2006)
        <doi:10.1007/0-387-30065-1_16>) Fortran 77 code
        <https://github.com/libprima/prima/tree/main/fortran/original>,
        as modified and distributed in the 'minqa' package, whose R
        interface is reproduced.
