		### Tiny utility to de-duplicate lists.
		### Tiny utility to create unions and de-duplicated lists.

		@@ -11,18 +11,26 @@ Example:
		var foo = { foo: 23 };
		var list = [ 3, 2, 2, 1, foo, foo ];
		var list = [3, 2, 2, 1, foo, foo];

		console.log(uniqs(list));
		uniqs(list);
		// => [3, 2, 1, { foo: 23 }]
		```

		Output:
		You can pass multiple lists to create a union:

		```js
		[ 3, 2, 1, { foo: 23 } ]
		uniqs([2, 1, 1], [2, 3, 3, 4], [4, 3, 2]);
		// => [2, 1, 3, 4]
		```

		Passing individual items works too:
		```js
		uniqs(3, 2, 2, [1, 1, 2]);
		// => [3, 2, 1]
		```

		### Summary

		* Uniqueness is defined based on strict object equality.
		* The list does not need to be sorted.
		* The original list is not modified.
		* If the given argument is not _array-like_, an empty array is returned.
		* The lists do not need to be sorted.
		* The resulting array contains the items in the order of their first appearance.
