Add new way to structure the styleguide

[manuelmeister]

To group these stories into Atoms, Molecules and so on, Monocle has currently the ability to sort the stories based on their Component name (Organisation.Site:Component.Atom.Button). But this leads to very long component names in the usage. This prevents me from quickly getting the overview of an AFX snippet. Could we also introduce a different way of defining the structure?

I would love to structure the styleguide with adding slashes to the title:

@styleguide {
        title = "Components/Atoms/Example"
}

Do you think this could be possible?
