Ichthyostega bd70c5faec Invocation: pick up work on the render node spec
...at the point where I identified the need to parse nested terms.
The goals are still the same
 * write tests to ''verify connectivity'' of nodes generated by the new `NodeBuilder`
 * allow for ''extended custom attributes'' in the ProcID
 * provide the ability to mark specific parametrisations
 * build a Hash-Key to identify a given processing step

__Note Library__: this is the first time `lib::Several` was used to hold a ''const object''.
Some small adjustments in type detection were necessary to make that work.
Access to stored data happens through the `lib::Several` front-end and thus always includes
the const modifier; so casting any const-ness out of the way in the low-level memory management
is not a concern...
