/**
* This method is like `_.zip` except that it accepts an array of grouped
* elements and creates an array regrouping the elements to their pre-`_.zip`
* configuration.
*
* @static
* @memberOf _
* @category Array
* @param {Array} array The array of grouped elements to process.
* @returns {Array} Returns the new array of regrouped elements.
* @example
*
* var zipped = _.zip(['fred', 'barney'], [30, 40], [true, false]);
* // => [['fred', 30, true], ['barney', 40, false]]
*
* _.unzip(zipped);
* // => [['fred', 'barney'], [30, 40], [true, false]]
