Exception: Fuse operation cannot be performed

[jbrezmorf]

Happens in creating simplified Endorse transport geometry when trying to fuse a borehole cylinder (volume) with the rectangles (faces)

• simplified surrounding boreholes and tunnels.

Seems that this operation can only be done for the objects of the same dimension.

• More tests.
• Check dimensions before.
• Suggest possible workaround. In this case, we further cut the fused object (that includes the faces) from the surrounding box.

Other issue is with fragment. In fact this is probably substantial source of other issues partially solved by various copies.

1. fragment operation should preferably be applied symmetricaly. The tool objects become also fragmented and are usually deleted, however the dim_tag copy operation (and possibly other operations) just skip missing dimtags. We should provide checks of ObjectSet consistency before and after every operation at least in a sort of debug mode.
2. Performing operations on dim_tags implicitly affects its boundaries.

Seems that mapping dimtags to properties must be maintained globally at the factory level.

Notoric problems with regions specific for dimensions. Rather maintain regions just as string labels and then possibly create
separate region for every label-dim combination. Just before applying them (rather on the completed mesh).

test that set operations work also for empty objects (e.g. fragmenting by an empty fracture list)
