+simulating large systems with Gillespie's @dfn{Stochastic Simulation
+Algorithm} (SSA).  This package is the spiritual successor to the GillespieSSA
+package.  Benefits of this package include major speed improvements (>100x),
+easier to understand documentation, and many unit tests that try to ensure the
+package works as intended.")
