+Takes any input and guarantees an array back.

+- converts any another other, singular value (including `null`) into an array containing that value
+- ignores input which is already an array
+
+**Kind**: Exported function  
+
+| Param | Type | Description |
+| --- | --- | --- |
+| input | <code>\*</code> | the input value to convert to an array |
+
+**Example**  
+```js
+> a.arrayify(undefined)
+[]
+
+> a.arrayify(null)
+[ null ]
+
+> a.arrayify(0)
+[ 0 ]
+
+> a.arrayify([ 1, 2 ])
+[ 1, 2 ]
+
+> function f(){ return a.arrayify(arguments); }
+> f(1,2,3)
+[ 1, 2, 3 ]
