// Unit-test API for nasal
//
// There are two versions of this module, and we load one or the other
// depending on if we're running the test_suite (using CppUnit) or
// the normal simulator. The logic is that aircraft-developers and
// people hacking Nasal likely don't have a way to run the test-suite,
// whereas core-developers and Jenksin want a way to run all tests
// through the standard CppUnit mechanim. So we have a consistent
// Nasal API, but different implement in fgfs_test_suite vs
// normal fgfs executable.
