Some further tweaks to the logic to allow using the `FeedPrototype` in the default setup,
where ''nothing shall be done with parameters...''
Provide the basic constructors and a type constructor in FeedManifold,
so that it is possible to install a ''processing functor'' into the prototype
and then drop off a copy into each new `FeedManifold`
With this additions, can now **demonstrate simple usage**
__Remark__: using the `DiagnosticBufferProvider` developed several years ago;
Seems to work well; however, when creating a new instance in the next test case,
we get a hard failure when the previous test case did not discard all buffers.
Not sure what to think about that
* for one, it is good to get an alarm, since actually there should not be any leak
* but on the other hand, `reset()` does imply IMHO „I want a clean slate“
Adding some code thus to clean out memory blocks marked as used.
When a test wants to check that all memory was released, there are tools to do so.
