This just changes placement behavior of vanilla buildings.
It takes certain buildings and makes them "combine" into a single entity. They still perform the same as the singular entities, and still give you the same items back when you mine them. The difference is, for UPS calculations, it's less entities.

Entities currently supported:
Steam Turbine (double and quad) (double and quad cannot be placed in blueprints. The singles will turn into doubles and quads as bots build the singles.)

Steam Engines (double and quad)

Entities to be supported:
Storage tank
Other buildings that get tiled often and do the exact same thing and are UPS intensive in large quantities.
