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.

@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]]
