Updated light scattering value.

The result is the same as used in the latest arXiv pre-print, scaled according to system size. Also removed redundant cells and updated gitignore file.
Fixed: Missing function in Math. fluor. simulator.

The init function `ImportNetworkFromYAML` had not been a part of the repository.
Updated control file for simpler output.
Merged MatLab scripts.
