extending SM model file

Yukawa couplings should be calculated automatically.
Set SUSY scale to value of SM vev v.
split beta-function according to dimensionality for non-SUSY models
add model information flag (SUSY model or not)?
adding flag about SUSY model type to model info output
proper indentation
adding SM with extra singlet (for testing FlexibleBSM)
make renormalization scheme selectable
select MS-bar renormalization scheme in the SM
correct capitalization of ren. scheme
correcting check for RGE files for non-SUSY models
account for renormalization scheme in threshold corrections
add Higgses to list of SM particles for the SM model
set MS-bar -- DR-bar conversion CTs to zero
renormalize SM in DR-bar scheme for easy matching to SUSY model
add charged and CP-Odd Higgs to list of SM particles (goldstones)
do not export NSM, as it is at the moment just for testing
