//
//   Rectangular bending magnet class
//   - itsLength parameter internally stores the geometrical length 
//   - itsAngle parameter internally stores the bending angle
//   - to get the arc length use the GetArcLength() function
//   - the volume is a trapezoid with pole faces perpendicular to the ideal
//     orbit
