class THaTwoarmVertex: public THaPhysicsModule, public THaVertexModule


 Calculate the intersection of the Golden Track from two spectrometers.
 The resultsing vertex coordinates are in global variables x,y,z.

 This module assumes that the spectrometers only reconstruct the
 target position transverse to the bend plane (y_tg) with relatively
 high precision. Each spectrometer therefore reconstructs a
 "track plane" spanned by the particle's momentum vector and the
 TRANSPORT x-vector, whose origin is the y-target point.

 The intersection of the two Golden Tracks is thus actually a line
 with undefined y_lab coordinate. This module always sets y to zero.
 The actual y_lab position can be derived from the beam position and
 is calculated in the THaPhysVertex and THaPhysAvgVertex modules.
