* @memberOf R
* @since v0.1.0
* @category Object
* @sig [k] -> {k: v} -> {k: v}
* @param {Array} names an array of String property names to copy onto a new object
* @param {Object} obj The object to copy from

* @see R.pick
* @example
*
* R.pickAll(['a', 'd'], {a: 1, b: 2, c: 3, d: 4}); //=> {a: 1, d: 4}
* R.pickAll(['a', 'e', 'f'], {a: 1, b: 2, c: 3, d: 4}); //=> {a: 1, e: undefined, f: undefined}
