Differentiable programming for Rust

This package is no more than sugar for existing Rust autograd libraries.

```rust
autograd!{
   let x; let y;
   let z = 2.*x*x + 3.*y + 1.;

   assert_eq!(eval (dz/dy), Ok(3.0));
   assert_eq!(eval [x=2.] (dz/dx), Ok(8.0));
   assert_eq!(eval (ddz/dx), Ok(4.0));
};
```
