*
* Deconstructs an array field from the input documents to output a document for each element.
* Each output document is the input document with the value of the array field replaced by the element.

* @memberOf R
* @since v0.28.0
* @category Object
* @sig String -> {k: [v]} -> [{k: v}]
* @param {String} key The key to determine which property of the object should be unwind
* @param {Object} object The object containing list under property named as key which is to unwind
* @return {List} A new list of object containing the value of input key having list replaced by each element in the object.
* @example
*
* R.unwind('hobbies', {
* name: 'alice',
* hobbies: ['Golf', 'Hacking'],
* colors: ['red', 'green'],
