After the last commit there were a few places needed to be adjusted to support subscriptions. This is done and a test case is added. It is important to implement subscriptions now, because they require changes to the library API, and they are a big missing part to finish the executor. When the executor is finished, we can start to provide more stable API without breaking everything every release. Validation and introspection shouldn't require much changes to the API; AST would require some changes to report good errors after the validation - this is one thing I can think of. Fixes #5.
