FFI integration proceeding apace. This means that the Rust bindgen tool has digested simh/sim_defs.h

So no-std bindgen is out. Turns out bindgen relies on std:: for its work. Rethinking the integration piece

Integration with simh looks like it will confined to using the FFI to call into Rust from the simh public API.

This is the time to thank Phil Koopman, PJK, for his trailblazing work documenting the RTX2001A. This project would not be possible without his work on the RTX2000 simulator.
