Added a vignette.
rs_matrix()
is about twice as fast now.
Making the "Y" vector with rs_matrix() no longer gives an error with length-0 inputs and a factor with non-empty levels.
rs_matrix() cleans up the enclosing environment of its result.
rs_pairs() has been reworked to be much faster and more general, while rs_unpair() has been removed. These changes are not backwards compatible.
Added French translations.
Fixed the NOTE about LazyData from CRAN.
