The most tedious aspect of this objective was dealing with the typecasting needed for integer and float arithmetic. I won't discuss strong typing/rust arguments or any of that, but the crux of issues here came down to a few competing philosophies.

I brought in the provided unit tests for `note_to_key_offset` and `chord_to_note_offset`. These turned out to be rather useful for ensuring my functions of the same name worked correctly. I began adding some tests for `make_notes` and may do the same for other functional units. I could move the tests into another source file, but decided not to, as to better parallel the source material.

`popgen.rs` seems to work ok. I have done some testing with various root note inputs and other parameters, but not exhaustively. Similar to `popgen.py`, some note clicking is audible
## Access outputs
Two output files were generated. I must have a slight bug in the `save` function, because these sound of somewhat lower quality.
