Description: 
    Fit linear and generalized linear mixed-effects models.  The
    models and their components are represented using S4 classes and
    methods.  The core computational algorithms are implemented using
    the 'Eigen' C++ library for numerical linear algebra and
    'RcppEigen' "glue".
