with the additional range cut parameter created Physics Helper object
the DD4hepSimulation physicsList attribute is now deprecated, use physics.list instead
The default value for the rangecut is the one from geant4 10.1: 700 micron

None is default for setupFuction, so we can allways pass the action and don't need the else
setupSD now accepts tuples

DDSim: use different name for different GenAction when the same kind of inputfile is used multiple times

if not specific filter is set the default filter for tracker or calorimeter is applied (if a default filter is set)
To turn off all filters just assign an empty string, empty list or None to the mapDetFilter

update doc

Move applyFilter to Helper/Filter
Adapt steeringFile

Move module doc to class doc so we can use it in the automatically created steering file

Change docstrings to be more sensible

changed member variables to private: _errorMessages, _dumpParameter, _dumpSteeringFile

removed abspath from macroFile and compactFile because otherwise the default values break error checking

See example/steeringFile.py and DDSim/Helper/Filter.py for examples

see the steering file or the ConfigHelper/Action docstring for an example for CaloPreShowerSDAction

use absolute path for steering, compact and macro file
remove magneticFieldDict because no longer used

in command line for example "--action.mapActions 'tcp TPCSDAction'"
or see example/steeringFile.py

ddsim: remove some commented lines, add dump[Parameter] flag to just print the configuration parameters

   which is the default location on more OSs
   except SL ...

   to avoid conflicts on case-insensitive OSs

* Move DD4hepSimulation et al into python module DDSim, needed for proper
  importing

* Can now control magneticfield setup, gun, particle handler, output via command
  line.

** added ConfigHelper and daughter classes implementing these options
   DDSim/DDSim/Helper, easily extensible to additional features

** also easier changing of these parameters via steering file See
   example/steeringFile.py

*** No more functions, no more "global GeV"

** --help string can be given by using @property, see e.g. Helper/Output.py

* added optional argcomplete, allows command line "tab"complete for all command line options (and values!)
  Needs argcomplete (sudo pip install argcomplete), bash completion and bash (or zsh).
  and 'eval "$(register-python-argcomplete ddsim)"'

* move import statements to reduce startup time until "--help", mandatory to
  reduce latency for argcomplete

Move DD4hepSimulation.py and RunProg.py to DDSim folder
Rename RunProg.py to ddsim
Add cmake install for DD4hepSimulation to lib/python, ddsim to bin which is already in PATH
