"Small vector" optimization for Rust: store up to a small number of items on the stack

## Example

```rust

use smallvec::{SmallVec, smallvec};

    

// This SmallVec can hold up to 4 items on the stack:

let mut v: SmallVec = smallvec![1, 2, 3, 4];

// It will automatically move its contents to the heap if

// contains more than four items:

v.push(5);

// SmallVec points to a slice, so you can use normal slice

// indexing and other methods to access its contents:

v[0] = v[1] + v[2];

v.sort();

```
