## new structure for the repository
- benchmarks are in `./benchmarks/` and can be run with either `cargo run --package benchmarks --bin <bench>` or the commands in `./benchmarks/README.md`
```

```

- examples are now in `./bins/` as standalone binaries and can be run either with `cargo run --package <pkg>` or with the help of the `cargo bin` command from `.nushell/cargo.nu`

- Nushell modules are now located in `./.nushell/`

## changelog
apart from the changes to the general structure of the repo:
- `binary.nu` -> `.nushell/binary.nu`
- new `cargo bin` command from `.nushell/cargo.nu`
- `error throw` is now defined in `.nushell/error.nu`
- main TOML has been greatly simplified because the dependencies of "examples" have been moved to the associated crates
- the rest is basically the same but in the new structure

check for empty inputs in the `run.nu` scripts

up until now, elliptic curves have been hardcoded in the benchmarks, forcing to run them on all supported curves...

this MR makes it possible to use only a subset of curves.

> 💡 **Note**  
> when running the same commands from !104, minus the "inbreeding" ones which are not affected by this MR, the time goes from 12min 33sec to 4min 28sec 🎉 


## TODO
- [x] setup
- [x] commit
- [x] recoding
- [x] fec
- [ ] linalg
- [ ] setup size
- [ ] field operations
- [ ] group operations

> 💡 **Note**  
> because all the unticked bullet points above are far from critical to the paper and do require to measure all curves, i won't change these for now

this MR moves run and plot commands from `examples/benches/README.md` to
- `scripts/setup/`: `run.nu` and `plot.nu`
- `scripts/commit/`: `run.nu` and `plot.nu`
- `scripts/recoding/`: `run.nu` and `plot.nu`
- `scripts/fec/`: `run.nu` and `plot.nu`
- `scripts/inbreeding/`: `build.nu`, `run.nu` and `plot.nu`

to generate all the figures at once
```bash
use scripts/setup/run.nu; seq 0 13 | each { 2 ** $in } | run --output data/setup.ndjson
use ./scripts/setup/plot.nu; plot data/setup.ndjson --save ~/setup.pdf

use scripts/commit/run.nu; seq 0 13 | each { 2 ** $in } | run --output data/commit.ndjson
use ./scripts/commit/plot.nu; plot data/commit.ndjson --save ~/commit.pdf

use scripts/recoding/run.nu; seq 0 18 | each { 512 * 2 ** $in } | run --ks [2, 4, 8, 16] --output data/recoding.ndjson
use ./scripts/recoding/plot.nu; plot data/recoding.ndjson --save ~/recoding.pdf
