af18a8e7d1 Write a deployment packaging script (#113)
All checks were successful
/ test (push) Successful in 3m38s
Adds a packaging script to help automate deployment. Documents the deployment process in `README.md`.

Also, moves `run-examples.sh` into the tools folder that we created for the packaging script.

ef1a579ac0 refactor: Code formatting (#108)
All checks were successful
/ test (push) Successful in 3m34s
Primarily, switch to using trailing commas. Also uniformizes commas with respect to switch branches, makes function call layout more consistent, line breaking more consistent, alphabetizes imports, uses the field init shorthand when possible, etc.

Resolves #99.

2eba80fb69 Simplify the realization triggering system (#105)
All checks were successful
/ test (push) Successful in 3m44s
Simplifies the system that reactively triggers realizations, at the cost of removing the preconditioning step described in issue #101 and doing unnecessary realizations after certain kinds of updates.

0801200210 Add more test assemblies (#103)
All checks were successful
/ test (push) Successful in 3m32s
This PR helps probe the capabilities of the engine.

Also adjusts the realization triggering system to reduce redundant realizations as we set an assembly's regulators during loading. Specificially, consolidates all calls to `realize()` into a single effect, which is triggered by the `needs_realization` signal.
Also introduces a `keep_realized` signal and use it to pause realization while loading assemblies, but this signal is planned for removal as ultimately we do not want a separate "mode" of interpreting commands during loading, for maximal reproducibility of results (and simplicity of system).

5864017e6f feat: Engine diagnostics (#92)
All checks were successful
/ test (push) Successful in 3m37s
Adds a `Diagnostics` component that shows the following diagnostics from the last realization:

- Confirmation of success or a short description of what failed.
- The value of the loss function at each step.
- The spectrum of the Hessian at each step.

The loss and spectrum plots are shown on switchable panels.

Also includes some refactoring/renaming of existing code.

### Install the prerequisites
1. Install [`rustup`](https://rust-lang.github.io/rustup/): the officially recommended Rust toolchain manager
* It's available on Ubuntu as a [Snap](https://snapcraft.io/rustup)
- It's available on Ubuntu as a [Snap](https://snapcraft.io/rustup)
2. Call `rustup default stable` to "download the latest stable release of Rust and set it as your default toolchain"
* If you forget, the `rustup` [help system](https://github.com/rust-lang/rustup/blob/d9b3601c3feb2e88cf3f8ca4f7ab4fdad71441fd/src/errors.rs#L109-L112) will remind you

3. Call `rustup target add wasm32-unknown-unknown` to add the [most generic 32-bit WebAssembly target](https://doc.rust-lang.org/nightly/rustc/platform-support/wasm32-unknown-unknown.html)
4. Call `cargo install wasm-pack` to install the [WebAssembly toolchain](https://rustwasm.github.io/docs/wasm-pack/)
5. Call `cargo install trunk` to install the [Trunk](https://trunkrs.dev/) web-build tool
6. Add the `.cargo/bin` folder in your home directory to your executable search path
* This lets you call Trunk, and other tools installed by Cargo, without specifying their paths
* On POSIX systems, the search path is stored in the `PATH` environment variable

- On POSIX systems, the search path is stored in the `PATH` environment variable
### Play with the prototype
1. From the `app-proto` folder, call `trunk serve --release` to build and serve the prototype
* *The crates the prototype depends on will be downloaded and served automatically*
* *For a faster build, at the expense of a much slower prototype, you can call `trunk serve` without the `--release` flag*
* *If you want to stay in the top-level folder, you can call `trunk serve --config app-proto [--release]`* from there instead.
- The crates the prototype depends on will be downloaded and served automatically
- For a faster build, at the expense of a much slower prototype, you can call `trunk serve` without the `--release` flag
- If you want to stay in the top-level folder, you can call `trunk serve --config app-proto [--release]` from there instead.
3. In a web browser, visit one of the URLs listed under the message `INFO 📡 server listening at:`
* *Touching any file in the `app-proto` folder will make Trunk rebuild and live-reload the prototype*
- Touching any file in the `app-proto` folder will make Trunk rebuild and live-reload the prototype
4. Press *ctrl+C* in the shell where Trunk is running to stop serving the prototype
### Run the engine on some example problems
1. Go into the `app-proto` folder
2. Call `./run-examples`
* *For each example problem, the engine will print the value of the loss function at each optimization step*
* *The first example that prints is the same as the Irisawa hexlet example from the Julia version of the engine prototype. If you go into `engine-proto/gram-test`, launch Julia, and then*
1. Use `sh` to run the script `tools/run-examples.sh`
- The script is location-independent, so you can do this from anywhere in the dyna3 repository

you should see that it prints basically the same loss history until the last few steps, when the lower default precision of the Rust engine really starts to show
### Run the automated tests
1. Go into the `app-proto` folder
2. Call `cargo test`
### Deploy the prototype
1. From the `app-proto` folder, call `trunk build --release`
- Building in [release mode](https://doc.rust-lang.org/cargo/reference/profiles.html#release) produces an executable which is smaller and often much faster, but harder to debug and more time-consuming to build
- If you want to stay in the top-level folder, you can call `trunk build --config app-proto --release` from there instead
2. Use `sh` to run the packaging script `tools/package-for-deployment.sh`.
- The script is location-independent, so you can do this from anywhere in the dyna3 repository
- The call from the top level of the repository is:
```bash
sh tools/package-for-deployment.sh
```
- This will overwrite or replace the files in `deploy/dyna3`
3. Put the contents of `deploy/dyna3` in the folder on your server that the prototype will be served from.
- To simplify uploading, you might want to combine these files into an archive called `deploy/dyna3.zip`. Git has been set to ignore this path
