Domain-level DSL extension for AshNeo4j.

Attach to an Ash domain (directly or via a domain fragment) to write an additional label on every node in that domain.

defmodule Telco do
  use Spark.Dsl.Fragment,
    of: Ash.Domain,
    extensions: [AshNeo4j.DataLayer.Domain]

  neo4j do
    label :Telco
  end
end

defmodule Provider do
  use Ash.Domain, fragments: [Telco]
end

Nodes for resources in Provider will have :Telco written as an additional label on CREATE, giving the graph a semantically navigable axis.
