class TEveMagField


 Abstract base-class for interfacing to magnetic field needed by the
 TEveTrackPropagator.
 See sub-classes for two simple implementations.

 NOTE: Magnetic field direction convention is inverted.

TEveVectorD GetFieldD(Double_t x, Double_t y, Double_t z) const

 Track propgator uses only GetFieldD() and GetMaxFieldMagD(). Have to keep/reuse
 GetField() and GetMaxFieldMag() because of backward compatibility.

{ return GetField(x, y, z); }

Double_t GetMaxFieldMagD() const

{ return GetMaxFieldMag(); }

TEveVector GetField(Float_t , Float_t , Float_t ) const

{ return TEveVector(); }

{ return 4; }
