0007 
0008  Description: Generator of the ideal/fake conditions for the LorentzAngle.
0009 
0010  It receives input values with layer granularity and it is able to perform gaussian smearing or
0011  use a uniform distribution at the module level.
0012  Depending on the parameters passed via cfg, it is able to generate the values per DetId
0013  with a gaussian distribution and a uniform distribution. When setting the sigma of the gaussian to 0
0014  and passing a single value the generated values are fixed.
0015  For TID and TEC the decision to generate with a uniform distribution comes from the setting
0016  for the first layers of TIB and TOB.
0017 
0018  Implementation:
0019      Port of SiStripLorentzAngleGenerator and templated fake ESSource to an edm::ESProducer
