Roadmap and task list

[mmiller-max]

This issue serves as a roadmap for key features that are not yet implemented

GraphQL features not yet implemented

• Documents
  • Build query once and pass variables each time it is executed
  • Multiple operations in one request to a server
  • Multiple definitions in one request to a server (needed for fragments)
• Directives
• Fragments
• Inline Fragments
• Arguments on all fields (including output fields)

General improvements

• Global client Add global_graphql_client #4
• Schema introspection
  • Improve performance of query
  • See if query needs updating
  • Can we type the schema?
  • Add tests
• Check runtime dispatch with JETTest

What introspection features/queries would be useful?
