+Adds helper utilities `createDefaultResolvers`, `createPossibleTypesMap`, `generateEnumMocksFromSchema` and `mockCustomScalars` for those who want to manually create and configure their mock schema.
+
+Also renames `createHandler` to `createHandlerFromSchema`; `createHandler` now provides an API that will create the mock schema under the hood with default resolvers as well as enum and custom scalar mocks.
