[Clas12_software] gemc 2.4

[Maurizio Ungaro]

GEMC 2.4 was released on 6/19.

To use at JLAB, set the proper environment:

source /site/12gev_phys/production.csh 1.3.1

The latest clas12 geometries have been updated in /group/clas12. Please use /group/clas12/clas12.gcard as
the starting point for clas12 simulations.

Please report documentation inconsistencies. You can also report bugs / feature requests on github (link below).
There may be small changes in the way gemc is run (see the gcard field properties for example), or missing documentation in some cases.
Thank you for your patience.

What's new
----------

- electronic noise
- database mechanism in digitization
- field properties
- neutron cosmic rays
- material, sensitivity options
- physics process catalogues


Notes
-----

- Simulations with clas12 10^35 luminosity background may crash the geant4 navigation occasionally. We're investigating this.
- Some bugs may have been fixed in gemc or geant4. To use the latest development version:

  source /site/12gev_phys/production.csh devel


What's Coming
-------------

The next version of gemc (2.5, currently "devel") will have the translation table mechanism and FADC output:
GEMC output will be the same as what comes out of data acquisition. In addition we'll have an improved GDML (and possibly CAD) interface.

The development version of gemc introduces external mblibraries. GEMC is being slowly re-written and re-organized into
separate libraries that makes use of advanced C++11 features and makes the code more object oriented. This will culminate in release 3.0.
