Improve examples settings

• use the dictionary for all parameters in every init.py
• include the model control.h within the model or config.h
• group dam break 2D experimental data to single file, so loading is unified with the simulation results (and 3D experimental data)
• read constants required by postpro.py from config.ini
• fix the variable --number-of-boundary layers in WCSPH_BI
• improve the way genCase is called in dam break 3D, remove the shell script
• in init.py use formatted strings
• rename ParticleSys to ParticlesType in config.h files
• in examples with periodic BC, there is inlet/outlet keywoard instead of left/right periodicity
