// Accepts a Prismic document and a url type.
// Uses the route definition to map document fragments to url params, and
// gets the domain name from config to output full urls.
// For route '/project/:slug/:id', the link resolver will output the
// domain name, append 'project' since it isn't a variable, and for each
// param that starts with a :, it will try to get the value from the document.

// TODO: Lacks support for all routes (*)
