take longitudinal wake in front into account - to be tested still ...
Merge branch 'master' of https://github.com/like2000/PyHeadTail into HBartosik
correct slices.slice_constant_charge, center the binning around bunch.mean_dz, implement multiple longitudinal resonators (by passing the resonators as array)
Work on bunch.py e-cloud implementation and add some minor cosmetics.
Add scatter to grid_functions.pyx and implement pusher in solvers.
prepare for fixed slices option, some fixes in bunch.slices, change BenchMark_BBresonator_longitudinal.py to precomupute wakefunction from BB resonator and use the interpolated wake table
Record intermediate status in implementation of poisson solver; runnign example, poisson structure implemented via injection.
Add slimmed down bunch monitor.
Add fields calculation to Poisson solver.
Add some suggestions for an improved structure.
Merge branch 'HBartosik' of https://github.com/like2000/PyHeadTail into kli
Add new compact particle monitor.
Successfully benchmark Poisson solver.
