v2.2.0

(I wasn't sure whether this should be considered to be a bug fix or new feature, but I went with new feature instead)

New

• Consider docblock above decorator annotations (#18). In the following example the docblock is now used for the component description:

  /**
  * This is the description
  */
  @SomeDecorator
  export default class extends React.Component {
  
  };

• Detect isRequired in shape annotations (second part of #21)
