Homu f9d36e6d9b Auto merge of #283 - cuviper:more-num, r=cuviper 
Add new traits for reference and assignment operators

There are two new "utility" traits covering the basic operators:
`Add`, `Sub`, `Mul`, `Div`, and `Rem`.

- `NumOps<Rhs, Output>`: operators with an arbitrary operand and output.
- `NumAssignOps<Rhs>`: assignment operators with an arbitrary operand.

Then the new collection of numeric traits are:

- `Num`: effectively unchanged, just taking operands by value.
- `NumRef`: `Num` adding reference operands on the right side.
- `RefNum`: `&T` operators, with either `T` or `&T` on the right side.
  - This does not specify `T: Num`, as rust-lang/rust#20671 means that
    could only add a constraint, without implying its presence for use.
- `NumAssign`: `Num` adding assignment operators by value.
- `NumAssignRef`: `NumAssign` adding reference assignment operators.
  - Nothing actually implements this yet!

Acknowledgement: this is roughly based on [@andersk's suggestion](https://github.com/rust-num/num/issues/94#issuecomment-269073071).

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.

Documentation

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.
