Minimal Observable interface to watch for object modifications.

## Installation

```console
npm install --save with-subscribe
```

## Usage

On a constructor:
```js
class Counter {
  constructor() {
    this.count = 0
  }

  increment() {
    this.count += 1
  }
}
const CounterWithSubscribe = withSubscribe(Counter)
const counter = new CounterWithSubscribe()

counter.subscribe(() => console.log('State:', counter.count)) // -> State: 0

counter.increment() // -> State: 1
counter.increment() // -> State: 2
```

As a decorator:
```js
@withSubscribe
class Counter {
  constructor() {
    this.count = 0
  }

  increment() {
    this.count += 1
  }
}
const counter = new Counter()

counter.subscribe(() => console.log('State:', counter.count)) // -> State: 0

counter.increment() // -> State: 1
counter.increment() // -> State: 2
```

On an object:
```js
const counter = withSubscribe({
  count: 0,
  increment() {
    this.count += 1
  }
})

counter.subscribe(() => console.log('State:', counter.count)) // -> State: 0

counter.increment() // -> State: 1
counter.increment() // -> State: 2
```
