// Class for the fast simulation of the muon trigger efficiency
// The trigger parametrization is computed for background levels 0., 0.5 and 1.
// In order to set a background level different from 0 it is necessary to 
// explicitly force it with:
// ForceBkgLevel(BkgLevel).
// For intermediate background levels, the trigger response is linearly 
// interpolated between these values.
// There is increased granularity in the pT region below 3 GeV. Although
// it does not seem to be necessary it is also possible to interpolate
// between pT bins using SetInt().
