## Linear mixed-effects models using Eigen and S4

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".
