Description

react-docgen is unable to find stateless function components that don't contain JSX or React.createElement call expressions.

This might be the case when some helper library is used. This will also fail if the official React.DOM helpers are used (https://github.com/reactjs/react-docgen/pull/71). Another failing case would be if only React components are returned, but React.createElement was never called because the components were wrapped in React.createFactory.

What about adding support for another heuristic, such as having a propTypes property (and to be even more specific, a propTypes property with an object containing React.PropTypes entries).

I'm happy to implement this and add tests if this sounds reasonable to the maintainers.

Research direction

Start by tracing the existing stateless function component detection in react-docgen and reviewing tests for components using React.createElement. Compare the proposed propTypes heuristic against React.DOM helpers and React.createFactory cases; done means these components are detected without breaking existing detection behavior and tests cover the supported patterns.
