Feature

Implement GraphQL fragments in sample GraphQL files

• GraphQL fragments are the way to make queries and mutations effectively. We have not use fragments in our sample application which makes queries really long and hard to maintain.
• Fragments are almost always used in clients due to the fact of reusability.

Our example application should use fragments (and library should support them)
