Admin App Applications & Application Instances

[seanrcollings]

Implements support for Applications & Application Instances in atomic-admin

Related to: https://github.com/atomicjolt/atomic-admin/pull/31

Implements the concept of "Interactions" which are ways in which the admin app can interact with information contained without each of the apps. Interactions can be things like:

• Analytics
• Forms for modifying a record
• Tables for listing records

The app determines what interactions it supports in an initializer, for example

# config/initializers/atomic_admin.rb

AtomicAdmin.application_instance_interactions.tap do |inter|
  inter.add(
    :analytics,
    type: :analytics,
    title: "Analytics",
    icon: "bar_chart",
  )

  inter.add(
    :general_settings,
    type: :jsonform,
    title: "General Settings",
    icon: "settings",
    # for schemas that all the apps will use, essentially unchanged, there 
    # be ones builtin to the gem, but the app can also implement it's own schemas if it 
    # so chooses
    schema: AtomicAdmin::Schema::ApplicationInstanceGeneralSettingsSchema
  )
end

Would make an "Analytics" and "General Setting" tab available for each app instance in the app.
