Move num-bigint to its own repo

All the prior `num` history is kept, so old `num-bigint` tags are still
valid, but future development here will be just for `num-bigint`.

-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](http://rust-num.github.io/num)
+Big integer types for Rust, `BigInt` and `BigUint`.
 
 ## Usage
 
 Add this to your `Cargo.toml`:
 
 ```toml
 [dependencies]
-num = "0.1"
+num-bigint = "0.1"
 ```
 
 and this to your crate root:
 
 ```rust
-extern crate num;
+extern crate num_bigint;
 ```
 
 ## Compatibility
 
-Most of the `num` crates are tested for rustc 1.8 and greater.
-The exception is `num-derive` which requires at least rustc 1.15.
+The `num-bigint` crate is tested for rustc 1.8 and greater.
