Opal maps

This MR will implement Map tracking for:

• Quadrupole
• Dipole
• Drifts
• Bends

TODO list:

• Code implementation (@ganz_p): ThickTracker, Hamiltonian, MapAnalyser
• Doxygen documentation (@ganz_p)
• Documentation (@ganz_p)
• Code cleaning (@frey_m)
• Regression tests (@snuverink_j)
• Examples (@ganz_p)
• Jupyter notebook (@ganz_p)
• Use beam line order

Remaining issues:

• Output dumps in local coordinates only
• Dipole until 1st order
• Tune calculation not stable
• Space charge calculations needs to be verified
• Fringe fields for Bends
