Functions to connect the widely used Storm Water Management Model (SWMM)
of the United States Environmental Protection Agency (US EPA)
<https://www.epa.gov/water-research/storm-water-management-model-swmm> to R with
currently two main goals: (1) Run a SWMM simulation from R and (2) provide fast
access to simulation results, i.e. SWMM's binary '.out'-files. High performance is achieved
with help of Rcpp. Additionally, reading SWMM's '.inp' and '.rpt' files is supported to
glance model structures and to get direct access to simulation summaries.
