Storybook: Displaying docs inside the storybook

At the moment the only way to display docs is the use of:

storiesOf('Main story', module)
  .add('some configuation, () => (
    <SomeComponent />
  )).(...)

This is insufficient for most our components...

In our use case it would be nice if we:

1. could add some more description (like an optional description tag for the story)

storiesOf('Main story', module, 'This component can be used to ... and has the following params ...')
  .add('some configuation, () => (
    <SomeComponent />
  )).(...)

1. or even better somehow reads the jsdocs in the js files and displays them above the component examples:

/**
 * Represents a book.
 * @constructor
 * @param {string} title - The title of the book.
 * @param {string} author - The author of the book.
 */

I think this is somehow related to #56 but not quite the same.
