After the complete makeover of the `FeedManifold` structure, which among other entails a switch from ''buffer arrays'' to tuples and the ''introduction of a parameter tuple'', this changeset now switches the „downstream code“ of the builder and node invocation, relying on an largely identical invocation API. The partially finished NodeLink_test now **runs as before** but on top of a drastically more flexible and open infrastructure. Quite a feat.
