Tasty-hunit-compat

This package provides a proper integration of HUnit package with tasty testing framework.

Problem with tasty-hunit package is that it defines its own primitives so tests written using HUnit cannot work properly. In particular, HUnitFailure exception of HUnit package is not handled as assertion error.

One solution would be not to use HUnit at all, but we find this fragile and inconvenient.

This subproject should be moved to a separate repository soon.
