> Extend using a decorator!

## Example

Given two classes *Hi* and *Boo*, extend *Hello*.

```javascript

// part 1a

class Hi {

  sayHi () {

    return 'hi'

  }

}

export default Hi

```

```javascript

// part 1b

class Boo {

  sayBoo () {

    return 'boo'

  }

}

export default Boo

```

```javascript

// part 2

import extend from 'extend-decorator'

import Hi from './Hi'

import Boo from './Boo'

@extend(Hi)

class Hello {

  constructor ($hello) {

    $hello.innerHTML = this.sayHi() // hello

  }

  sayHi () {

    return 'hello'

  }

}

@extend(Hi, Boo, true)

class HelloOverwrite {

  constructor ($helloOverwrite) {

    $helloOverwrite.innerHTML = `${this.sayHi()} and ${this.sayBoo()}` // hi and boo

  }

  sayHi () {

    return 'hello'

  }

}

```

If the last argument for `@extend()` is a boolean true, overwrite matching methods. To extend with more objects, just pass them as additional arguments i.e. `@extend(A, B, C)`.
