Mathematical expression evaluator with context and float methods

```rust
use mathew::Eval;

fn main() -> Result<(), ()> {
    let e = Eval::default().insert("foo", "1")?.insert("bar", "0")?;

    assert_eq!(e.eval("foo + bar").unwrap(), 1.0);
    
    assert_eq!(e.eval("foo - bar * 1").unwrap(), 1.0);
    
    assert_eq!(e.eval("1 + bar").unwrap(), 1.0);
    
    assert_eq!(e.eval("2.5.powi(2 * foo)").unwrap(), 6.25);

    Ok(())
}
```
