 *
 * 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
 *
