...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...
