Helper functions for prototypical inheritance in JavaScript.

Use the source code and JSDoc comments as documentation, here's a quick example to get you started.

```javascript

const heir = require('heir')

// Create the base class.

function Base() {}

// Add a method.

Base.prototype.foo = function () {

  return 'Base#foo'

}

// Create a sub class which inherits from base.

function Sub() {}

heir.inherit(Sub, Base)

// Mix in some functionality enhancing objects.

heir.mixin(Sub, events)

heir.mixin(Sub, pooling)

// Change the original method.

Sub.prototype.foo = function () {

  return [

    'Sub#foo',

    Sub._super.foo.call(this)

  ].join(', ')

}

// Create an instance of Sub and call it's method.

const s = new Sub()

s.foo() // Returns "Sub#foo, Base#foo"

```
