This module glue together parts of GraphQL schemas, based on their AST representation.

It makes it easier and simpler to merge GraphQL Types, enums, unions and interfaces.

# a1.graphql
type A {
    f1: String
}

# a2.graphql
type A {
    f2: String
}

Will result:

type A {
    f1: String
    f2: String
}
