Detailed Description

Generator of the ideal/fake conditions for the LorentzAngle.
It receives input values with layer granularity and it is able to perform gaussian smearing or use a uniform distribution at the module level.
Depending on the parameters passed via cfg, it is able to generate the values per DetId with a gaussian distribution and a uniform distribution. When setting the sigma of the gaussian to 0 and passing a single value the generated values are fixed.
For TID and TEC the decision to generate with a uniform distribution comes from the setting for the first layers of TIB and TOB.

void SiStripLorentzAngleGenerator::setHallMobility	(	const double &	meanMin,
		const double &	meanMax,
		const double &	sigma,
		const bool	uniform
	)		`[private]`

This method fills the hallMobility_ variable with different values according to the parameters passed in the cfg.

If a min and max value were passed it takes the value from a uniform distribution.
If only a single value was passed and the error is set != 0 it takes the value from a gaussian distribution.
If the error is 0 and only one value is passed it takes the fixed min value.
