330: Implement *Assign for BigUint r=cuviper a=Darksonn
Not only does this change increase convenience of use, it also allows adding a `&BigUint` to a `&mut BigUint` without allocating (if not necessary) or tricks such as:
fn add(a: &mut BigUint, b: &BigUint) {
let aa = mem::replace(a, BigUint::from_slice(&[])); // BigUint::from_slice(&[]) does not allocate
*a = aa + b;
}
With this change:
fn add(a: &mut BigUint, b: &BigUint) {
*a += b;
}
It would make sense to add the same functionality to `BigInt`, but it uses some macros to handle the signs, and I'm not sure how to change the macros in order to perform this change.

num
A collection of numeric types and traits for Rust.
This includes new types for big integers, rationals, and complex numbers,
new traits for generic programming on numeric properties like Integer,
and generic range iterators.
Usage
Add this to your Cargo.toml:
[dependencies]
num = "0.1"
and this to your crate root:
extern crate num;
Compatibility
Most of the num crates are tested for rustc 1.8 and greater.
The exceptions are num-derive which requires at least rustc 1.15,
and the deprecated num-macros which requires nightly rustc.
