Incoherent naming objects for the section intersection and DEM projection function

[gbene]

The section intersection function creates entities without the section name in the name (entity1_intersection). The function should be modified to be more coherent with the projection naming scheme (resulting in for example entity1intersectionsection_name).

OK, maybe we can make it shorter as in entity1_int_section_name.

Ok. I noticed the same problem for the projection to DEMs. We could name such entities as entity1_projected_DEM.

[andrea-bistacchi]

I suggest the shorter entity1_proj_DEM
