Better support for custom types

This is more of a "would you be willing to accept a pull request which does this?" question than an issue of sorts. :)

I would really like to extend the functionality of "custom" types so that:

1. We support destructured imports (Eg. PropTypes.array - note the lack of React.)
2. We allow common react-esque prop type function patterns to be picked up with custom props in the same way that arrayOf is currently handled. (Eg. PropTypes.iterableOf(PropTypes.record(User)))

Basically I feel the library should be able to support custom user prop types in such a way we don't have to reparse the raw value which would mean anyone can easily implement simple custom prop types and create documentation from that.

Custom prop types are super useful in building a real-world app with React and so I would like to see how we can help developers document these too.

We, at Lystable, want to build an open living component docs solution and are hoping react-docgen can feature at the core!

Aucun fichier, test ou point d’entrée n’est nommé. Commencez par localiser la gestion existante de custom prop-type et le chemin de code qui gère arrayOf, puis déterminez comment les imports déstructurés et les fonctions personnalisées imbriquées sont représentés. Le travail est terminé lorsque les deux modèles demandés sont documentés sans réanalyser la valeur brute, avec une couverture pour les exemples fournis.
