Rust Sundials

=============

[Sundials][] is a s̲u̲ite of n̲onlinear and d̲i̲fferential/a̲l̲gebraic

equation s̲olvers.

# Example

The following code solves the equation ∂ₜu = f(t,u) where f is the

function (t,u) ↦ 1 using Adams' method.

```rust

use sundials::{context, cvode::CVode};

fn main() -> Result<(), Box> {

    let mut ode = CVode::adams(0., &[0.], |t, u, du| *du = [1.])

	    .build(context!()?)?;

	let mut u1 = [f64::NAN];

	ode.solve(2., &mut u1);

	assert_eq!(u1, [2.]);

    let (u2, _) = ode.cauchy(0., &[0.], 1.);

    assert_eq!(u2[0], 1.);

    Ok(())

}

```

Then `u[0]` contains the solution u at time t=1 and `u[1]` the

speed ∂ₜu(1).
