Add a monitor module to save tracking data based on h5py
Bunch Monitor is used to get statistics from a specific bunch
PhaseSpaceMonitor is used to save the phase space of a specific bunch
For now the .hdf5 file is opened and closed at each write operation, this seems to cause some problems for mpi.

Update machines/__init__.py, machines/soleil.py, tracking/__init__.py, tracking/aperture.py, tracking/element.py, tracking/optics.py, tracking/parallel.py, tracking/particles.py, tracking/rf.py, tracking/synchrotron.py files
