/**
* The inverse of `_.pairs`; this method returns an object composed from arrays
* of property names and values. Provide either a single two dimensional array,
* e.g. `[[key1, value1], [key2, value2]]` or two arrays, one of property names
* and one of corresponding values.
*
* @static
* @memberOf _
* @alias object
* @category Array
* @param {Array} props The property names.
* @param {Array} [values=[]] The property values.
* @returns {Object} Returns the new object.
* @example
*
* _.zipObject([['fred', 30], ['barney', 40]]);
* // => { 'fred': 30, 'barney': 40 }
*
* _.zipObject(['fred', 'barney'], [30, 40]);
