Contributions summary:Jesper implemented a new feature adding "afterwares" to the Apollo Client network interface, allowing for handling responses after middlewares. This involved modifying `networkInterface.ts` and creating `afterware.ts` to define interfaces. Unit tests were also added to `test/networkInterface.ts` to verify the new afterware functionality. Additionally, the user updated the `index.ts`, `QueryManager.ts` files, and related tests by adding `batchInterval`.
