R and 'Eigen' integration using 'Rcpp'.
 'Eigen' is a C++ template library for linear algebra: matrices,
 vectors, numerical solvers and related algorithms.  It supports dense
 and sparse matrices on integer, floating point and complex numbers,
 decompositions of such matrices, and solutions of linear systems. Its
 performance on many algorithms is comparable with some of the best
 implementations based on 'Lapack' and level-3 'BLAS'.

   The 'RcppEigen' package includes the header files from the 'Eigen' C++
 template library (currently version 3.2.9). Thus users do not need to
 install 'Eigen' itself in order to use 'RcppEigen'.

   Since version 3.1.1, 'Eigen' is licensed under the Mozilla Public License
 (version 2); earlier version were licensed under the GNU LGPL version 3 or
 later. 'RcppEigen' (the 'Rcpp' bindings/bridge to 'Eigen') is licensed under
 the GNU GPL version 2 or later, as is the rest of 'Rcpp'.
