Save area from spot to linked hierarchy object

Saving area from vector objects on drawing to linked hierarchy object is possible based on Layer Relations mapping.

First, Layer Relation must be created. It's a relation between specific layer and object's class field.
When invoking new functionality area from spot on layer from Layer Relations will be put into linked object's class field (defined in relation).

Save area functionality can be triggered from context menus in various places:

On selected Tree object (that is part of layer relation).

Using option from this place will save area from all spots on all layers that have layer relation defined to proper selected object's fields - based on layer relations.
On Drawing context menu (outside any spot area) we can save area from all spots and all layers (or selected layer) to linked objects based on defined layer relations.
On selected spot's context menu or pop-up properties. This will save area from all spots on all or selected layers linked to object from layers relation.

After operation is done, report will show information about which objects and fields were updated with what value.
