More structural transforms

[YingboMa]

• State selection
• Parallelization based on SCCs
• Use SCC to give better error in tearing

Are there useful additions in here?

Fine Dulmage-Mendelsohn decompositions are just another name for BLT or SCC.

There is a python package containing a lot of tearing algo here https://github.com/baharev/sdopt-tearing . it is the package written by baharev you have pointed out
blt ordering seems to be here https://github.com/baharev/sdopt-tearing/blob/master/blt_decomp.py

the modia one af course is here too https://github.com/ModiaSim/ModiaBase.jl/blob/main/src/BLTandPantelides.jl
