Reconsider some default switches

Description (last modified by Stefan Hoeche)

Some switches that we might want to consider as defaults in the next major version:

  • Max_Epsilon 1e-3 overweighting is correctly handled now
  • WRITE_MAPPING_FILE=3 [done]
  • GENERATE_RESULT_DIRECTORY=1 [done]
  • CSS_AS_*_FAC=0.4 [done]
  • FILE_SIZE should probably be unlimited.
  • Set widths of SM particles to their tree-level values?
  • ME_SIGNAL_GENERATOR="Internal Comix Amegic"

Please collect more that you would consider reasonable.

The old options to adjust coupling factors in the CSS (and POWHEG) are removed and replaced by CSS_AS_FAC (and PH_CSS_AS_FAC) with r17003. Their default is set to one, and the NLL value of ~0.406 is implemented directly by the colour function. Hence CSS_AS_FAC now acts as an _additional_ coupling prefactor, whereas before it included the non-dynamic part of the NLL correction.

Should we also set widths of SM particles to their tree-level values?

Leave SM particles width as they are, to not mess up comparison to data.

Should we also make 'GENERATE_RESULT_DIRECTORY=1' the default? As our setups become increasingly complicated it is probably also increasingly unreasonable not to store integration results.

GENERATE_RESULT_DIRECTORY=1 is default starting from r17266.

Changed Max_Epsilon from 1e-6 to 1e-3 in r17328 to improve unweighting efficiency.
