...written as byproduct from the reimplementation draft.
NOTE there is a quite similar test from 2013, DependencyFactory_test
For now I prefer to retain both, since the old one should just continue
to work with minor API adjustments (and thus prove this rewrite is a
drop-in replacement).
On the long run those two tests could be merged eventually...
This is a complete makeover of our lib::Depend and lib::DependencyFactory templates.
While retaining the basic idea, the configuration has been completely rewritten
to favour configuration at the point where a service is provided rather,
than at the point where a dependency is used.
Note: we use differently named headers, so the entire Lumiera
code base still uses the old implementation. Next step will be
to switch the tests (which should be drop-in)
