Just because I was annoyed that I couldn't use `Option<T>::zip` with more than 2 arguments...

Zips provides 2 proc-macros that accept any number of either `Option<T>`s or `Result<T, E>`s as arguments and produces an `Option<(T [, T...])>`.

## Installation
```sh
$> cargo add zips
```

## Usage

### With `Option<T>`:
```rust
use zips::zip;

fn main() -> () {
  let i: Option<i32> = Some(0);
  let j: Option<usize> = Some(1usize);
  let k: Option<()> = None;
 
  //  zipped_some: Option<(i32, usize)>
  let zipped_some = zip!(i, j);
  assert_eq!(zipped_some, Some((0, 1usize)));
 
  //  zipped_none: Option<((i32, usize), ())>
  let zipped_none = zip!(zipped_some, k);
  assert_eq!(zipped_none, None);
}
```

### With `Result<T, E>`:
```rust
use zips::zip_result;

fn main() -> () {
  let m: Result<i32, ()> = Ok(1);
  let n: Result<usize, ()> = Ok(0usize);
  let o: Result<(), &'static str> = Err("I'm an error!");
 
  //  zipped_ok: Option<(i32, usize)>
  let zipped_ok = zip_result!(m, n);
  assert_eq!(zipped_some, Some((1i32, 0usize)));
 
  //  zipped_err: Option<((i32, usize), ())>
  let zipped_err = zip_result!(zipped_ok, o);
  assert_eq!(zipped_err, None);
}
```
