ObservedZone

[mbeaufils]

A location that was subject to observations as defined by #19

The ObservedZone can be nested in another observation support such as a Borehole or a Trial Pit.

March17 decision to merge MappedZone with TestedZone to cover both Observations and Measurements

In the Miro diagram, I see that there are grey arrows which link the 'Observed zone' object to Borehole and trial pit objects.

For me, ObservedZone, Borehole and TrialPit object don't have Parent/Childhood relations as they are at the same level. I propose to delete the grey arrows.
