This module contains some instruments with Causal arrow interface.
The interface is a bit low-level
since you have to write the transformations of the Haskell-side
separately from the computations on the LLVM side.
A nicer integration is used in
"Synthesizer.LLVM.Server.CausalPacked.InstrumentPlug".
However, we preserve this module in order to show
how things work internally.
