Tensor network library in Rust.

## Installation

```bash
cargo add ariadnetor
```

`ariadnetor` is the component layer (tensors, linear algebra, MPS/MPO).
Tensor-network algorithms (DMRG, …) live in a separate crate:

```bash
cargo add ariadnetor-algorithms
```

### Optional features

Both are off by default, so a plain `cargo add` builds pure-Rust with no C/C++
or system-library dependency.

- **`hptt`** (`ariadnetor`) — routes tensor transposition through the
  [HPTT][hptt] kernel via the [hptt-rs][hptt-rs] bindings. Requires a C++
  compiler and CMake to build HPTT.
- **`arpack`** (`ariadnetor-algorithms`) — adds the [ARPACK-NG][arpack]
  eigensolver backend via the [arpack-rs][arpack-rs] bindings. Requires a
  system ARPACK library discoverable through `pkg-config`.
