Add meshing for moving domains and MovingAtrium.py

[hkjeldsberg]

• Add MovingAtrium.py, a highly modified version of Atrium.py for moving domain simulations in the atrium
• Collect common methods between the simulation scripts in simulation_common.py
• Add meshing steps for dynamic motion based on surface models
• Add Scipy as main dependency (MovingAtrium.py)
• Added demo model for moving atrium meshing and simulation
• Added documentation for moving meshing and moving simulations (tutorial)
