Optional dynamic segments

[jamesplease]

In tildeio/router.js#102, @mgenev expressed his frustration for dealing with a complex routing situation that he believed optional dynamic segments would resolve. @machty said he would support this were a PR made here in route-recognizer, so I'm creating this issue to document it as a todo.

Prior art:

Backbone

Optional segments are wrapped in parentheses. i.e. docs/:section(/:subsection)

React Router

A question mark marks the previous segment as optional. i.e. docs/:section?

However, React is apparently switching over to parentheses because of how annoying it is to deal with the question marks (ref: remix-run/react-router#960 )

@jmeas any solution for this?

Not that I'm aware of 😛

Closing this in favor of emberjs/rfcs#154.
