/**
* Implements prototypical inheritance by replacing the prototype of one constructor with the prototype of another constructor.
*
* ## Notes
*
* -   This implementation is not designed to work with ES2015/ES6 classes. For ES2015/ES6 classes, use `class` with `extends`.
* -   For reference, see [node#3455](https://github.com/nodejs/node/pull/3455), [node#4179](https://github.com/nodejs/node/issues/4179), [node#3452](https://github.com/nodejs/node/issues/3452), and [node commit](https://github.com/nodejs/node/commit/29da8cf8d7ab8f66b9091ab22664067d4468461e#diff-3deb3f32958bb937ae05c6f3e4abbdf5).
*
*
* @param {(Object|Function)} ctor - constructor which will inherit
* @param {(Object|Function)} superCtor - super (parent) constructor
* @throws {TypeError} first argument must be either an object or a function which can inherit
* @throws {TypeError} second argument must be either an object or a function from which a constructor can inherit
* @throws {TypeError} second argument must have an inheritable prototype
* @returns {(Object|Function)} child constructor
*
* @example
* function Foo() {
*     return this;
* }
* Foo.prototype.beep = function beep() {
*     return 'boop';
* };
*
* function Bar() {
*     Foo.call( this );
*     return this;
* }
* inherit( Bar, Foo );
*
* var bar = new Bar();
* var v = bar.beep();
* // returns 'boop'
