Implement Danilo's new slicing with some rather cosmetic corrections.
Complete full matched beam initialisation.
Again with constructor overloading in beam class.
Round up beam.py. Prepare test case for beam generation.
Move to beams module. Adapt slices class for new beam class. Rename some longitudinal tracker classes.
Again restructure beams module. Optimize spacecharge module a little and prepare for testing.
Next step in restoring beams module. Already prepared a placeholder for a Match class.
Merge branch 'kli' of https://github.com/like2000/PyHEADTAIL into kli
Merge branch 'kli' into rfq
Adapted Monitors and Wakefields to comply with the concept of Slices decoupled from Bunch. Ready for testing.
