add additional slice at the end of the bunch containing lost particles (plus modifications in beams/bunch.py, beams/slices.py, monitors/monitors.py), implement reading from wake table, add aperture class and implement losses, clean up beams/slices.slice_constant_space and beams/slices.slice_constant_charge (define methods beams/bunch.sort_particles and beams/bunch/set_in_slice methods, ...
add longitudinal BB resonator and longitudinal wake field kicks in impedances/wake_fields, addtransverse resistive wall impedance, add method to read in wake table from ASCII file, bug fix in bunch.compute_statistics related to the additional slice for lost particles, add bunch.n_particles_lost attribute, bug fix in bunch.determine logitudinal_cuts
change bunch.n_particles to bunch.n_macroparticles, change bunch.slices.charge to bunch.slices.n_macroparticles, introduce the possibility to read in particle distribution from file
