Expression evaluator with context
```rust
use v_eval::{Value, Eval};
fn main() -> Result<(), ()> {
let e = Eval::default()
.insert("foo", "true")?
.insert("bar", "false")?;
assert_eq!(e.eval("foo != bar").unwrap(), Value::Bool(true));
assert_eq!(
e.eval("true && foo != bar && true").unwrap(),
Value::Bool(true)
);
assert_eq!(e.eval("1 == 1 != bar").unwrap(), Value::Bool(true));
assert_eq!(e.eval("1 == 1 + 1 == bar").unwrap(), Value::Bool(true));
Ok(())
}
