Fork of Elm RFC5988 Parser

A (presently woefully incomplete) parser for the upcoming RFC5988 replacement draft, written in Elm using elm-combine for DailyDrip.

Example

There are some examples in the test suite, but here's one:

Expect.equal
  (parse rfc5988 "<http://noredink.com>; rel=\"start\"")
  ( Ok { context = "", target = "http://noredink.com", relationType = "start", targetAttributes = Dict.empty }
  , { input = "", position = 31 }
  )

Todo

There's a lot of stuff left to do here. Here's an almost-certainly-incomplete list:

• Handle context at all (I think we want to just partially-apply one when parsing in the first place?)
• Determine whether it makes any sense at all for relationType to have its own field.
• Determine if we should add other similar fields, if that was reasonable.
• There are almost certainly some fields that should have a Maybe type signature.
• If there are two rel parameters, there's a very specific callout in the spec that we're supposed to follow that we almost certainly aren't (but they aren't supposed to have them either!)
