## Description Hopefully this is relatively self-explanatory: this change splits the helper functions we've used to extend QuickCheck from the orphan instances and generators that we have defined for unit tests. These have now been placed in `Test.QuickCheck.Extended` and `Hasura.QuickCheck.Instances`, respectively. This change also adds some documentation to the functions defined in `Test.QuickCheck.Extended` in the spirit of similar functions defined by `Test.QuickCheck`, itself. ### Motivation We should adhere to the existing convention of constructing "extension modules" for common libraries separately from the code that takes advantage of these. Alone, this wouldn't be a reason to split up `Hasura.Generators`, but we should **also** follow a convention of defining **all** orphan instances in modules whose names clearly indicate that they exist solely for the purpose of exporting these orphan instances (e.g. `Hasura.QuickCheck.Instances`).
