%description
Tightens an observational block design into a smaller design with either
smaller or fewer blocks while controlling for covariates. The method uses
fine balance, optimal subset matching (Rosenbaum, 2012
<doi:10.1198/jcgs.2011.09219>) and two-criteria matching (Zhang et al 2023
<doi:10.1080/01621459.2021.1981337>).  The main function is tighten().
The suggested 'rrelaxiv' package for solving minimum cost flow problems:
(i) derives from Bertsekas and Tseng (1988) <doi:10.1007/BF02288322>, (ii)
is not available on CRAN due to its academic license, (iii) may be
downloaded from GitHub at <https://github.com/josherrickson/rrelaxiv/>,
(iv) is not essential to use the package.
