Deprecate `na::`, move all reexport to the root crate. 

This also moves the tests and benches to cargo-complient folders.

Fix #21.

## Using **nalgebra**
All the functionalities of **nalgebra** are grouped in one place: the `na` module.
All the functionalities of **nalgebra** are grouped in one place: the root `nalgebra::` module.
This module re-exports everything and includes free functions for all traits methods doing
out-of-place modifications.
* You can import the whole prelude using:
```.ignore
use nalgebra::na::*;
use nalgebra::*;
```
The preferred way to use **nalgebra** is to import types and traits explicitly, and call
free-functions using the `na::` prefix:
```.rust
extern crate nalgebra;
use nalgebra::na::{Vec3, Rot3, Rotation};
use nalgebra::na;
extern crate "nalgebra" as na;
use na::{Vec3, Rot3, Rotation};
fn main() {
let a = Vec3::new(1.0f64, 1.0, 1.0);

For example, the following works:
```rust
extern crate nalgebra;
use nalgebra::na::{Vec3, Mat3};
use nalgebra::na;
extern crate "nalgebra" as na;
use na::{Vec3, Mat3};
fn main() {
