there is now a mechanism to allow sprcialised queries
to generate this syntactic representation only on demand
The actual concrete representation e.g. for scope queries
still remains TODO, but this won't really change
until we target the integration of a real resoloution engine
...to extract the syntetic ordering from
DefsRegistry and make that a responsibility
of the (internal) syntactic representation
of the query.
doesn't pass the compiler yet
effectively this joins the two existing lines
of "Query" classes into one systematic representation
Next step would be to move all mutation operations
over to the Query::Builder
the rules-based configuration and query system
will be located within the core application,
while the concrete implementation facilities
are expected to reside within the session or
maybe also the GUI.
This is kind of a 'rochade' refactoring to resolve
circular library dependencies and confine the parts
dependant on the session and MObjects to the Proc-Layer
And while we're in the middle of chainsaw surgery,
we'll concentrate further query-based facilities
alongside the config-rules within the App core.
