## Project Setup
1. Create the project directory structure:
```bash
mkdir rhai-python
cd rhai-python
mkdir src python/rhai
```
2. Copy the provided files to their respective locations:
- `Cargo.toml` → project root
- `pyproject.toml` → project root
- `src/lib.rs` → src directory
- `python/rhai/__init__.py` → python/rhai directory
- `example_usage.py` → project root (for testing)
## Building
1. **Development build** (recommended for testing):
