The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.

transaction. For the current definition of SimDuration, this is

currently the number of nanoseconds. Submitter internally casts

arithmetic T to SimDuration::rep units to allow using standard

library distributions as a Distribution.
