Takes 2D GIS datasets (e.g. topographical datasets) and "3dfies" them (as in "making them three-dimensional") by lifting every polygon to 3D.

Our aim is to obtain one DSM that is error-free, i.e. no intersecting triangles, no holes (the surface is watertight), where buildings are integrated in the surface, etc.
This surface will then be used as input in simulation software for instance.

This video illustrates the process and what 3dfier is about.
The lifting options can be configured in the YAML file provided, an examples are provided in `/resources/config_files/myconfig.yml`.
