check reduction in computing time if radiation network is simplified #78

In the room model, the infrared radiation network leads to coupled linear or nonlinear equations which are often of the size 10 to 15. Check how computing time is affected if this is reformulated using a star network representation.

I did this comparison in IDEAS (https://github.com/open-ideas/IDEAS/pull/326). In our case a star network seems to be more efficient. Note that creating states on a wall's surface (https://github.com/open-ideas/IDEAS/issues/289) may reduce the linear system sizes, if this is not already the case.
