 response time analysis, schedule simulation, and schedule plotting.

+## Note To Researchers
+
+To foster more research collaboration, and enable broader code reuse, you are
+encouraged to submit your high-quality research code using this package to the
+`RealTimeScheduling.Papers` submodule.  If your code is very broadly
+applicable (e.g. new schedulability analysis for GEDF), then we would welcome
+it directly to the `RealTimeScheduling` package instead.
