Backend module to generate translation schemas for user of the trans library.

WHen defining structured translations for Ecto schemas the Trans documentation shows the following example

defmodule MyApp.Article do
  use Ecto.Schema
  use Trans, translates: [:title, :body]

  schema "articles" do
    field :title, :string
    field :body, :string
    embeds_one :translations, Translations, on_replace: :update, primary_key: false do
      embeds_one :es, MyApp.Article.Translation, on_replace: :update
      embeds_one :fr, MyApp.Article.Translation, on_replace: :update
    end
  end
end

Using the translate/3 macro in this module, the following will configure structued translations for all locales configured in this backend. An example is:

defmodule MyApp.Article do
  use Ecto.Schema
  use Trans, translates: [:title, :body]
  use MyApp.Cldr.Trans

  schema "articles" do
    field :title, :string
    field :body, :string

    # The translation module name and the options
    # may be ommitted - the defaults are those shown
    translations :translations, Translations, on_replace: :update, primary_key: false
  end
end
