+// Source simulation: Particle position/distance randomization
+// This class has functionality of randomizing particle positions / pair distances
+// so obtained correlation function follows a given shape,
+// depending on a value of fRandomPosition member
+// By default this feature is switched off: fRandomPosition == AliHBTLLWeights::kNone
+// It can be: kGaussianQInv - so 1D Qinv correlation function has a Gaussian shape
+// (and also Qlong and Qside, but not Qout)
+// kGaussianOSL - so 3D Qout-Qside-Qlong correlation function has a Gaussian shape
