Regarding seed initialization for surface hopping methods.

[jkha-unist]

1. Seeds must be initialized independently for different simulations.
2. A restarted simulation must have a consistent random number sequence with the original simulation.
   ex) A random number sequence for 0~1000 step = Appended random number sequences for 0~145 and for restarted 146 ~1000 step.

3. Add example run.py with a fixed seed.
