Make models streamable

[fahad19]

What's done

Models now support Observables, for streaming changes as they happen. This would be of very high impact for dealing with forms in observed React components.

Usage

Import:

import { createModel } from 'frint-model';

Create Model class:

const Shirt = createModel({});

Building a new model instance:

const shirt = new Shirt({
  color: 'blue',
  size: 'medium',
});

The model instance can also be observed for changes:

shirt.get$().subscribe(function (shirtAttributes) {
  // triggered when the model had any change
});

shirt.get$('color').subscribe(function (color) {
  // triggered when the model's `color` key changes
});

just curious, why you are not adding any description (eg jsdoc)?

[fahad19]

till now, we have always maintained the API documentation in package's own README whenever we made changes in code. but I agree jsdoc would be a better approach.

would really welcome PRs to speed that process up :)
