// Class for creation of quadrupole magnetic field
31
// fGradient - is the gradient value for quadrupole magnetic lense.
32
// Then the magnetic field components are:
33
// Bx = B[0] = fGradient*X ,
34
// By = B[1] = fGradient*Y ,
35
// Bz = B[2] = 0 .
36
// Here X,Y,Z are the coordinates of a space point of interest.

// 03.02.1997, V.Grichine - Created

// 11.05.2012, B.Riese - Allow displaced origin and rotation
