Changes the Heavy Ion config, so there's only only function creating
HIEventShapeMaker and it's in
HIGlobalConfig.py. The duplicated code from
HIEventShapeCfg()) is deleted.
The new function
HIEventShapeMakerCfg() can create both weighted and non-weighted event shapes via
HIGlobalConfig.py as it's more intuitive.
The output remains unchanged.
