Interpreting the output of gemc/evio2root

Coordinates: From Maurizio, "the "root" coordinate system has (0,0,0) as the center of the target, the z-axis along the beam, and the y-axis pointing up." Theta and phi "are the normal theta and phi definition of a 3-vector in a coordinate system: Theta is the angle with the z-axis. Phi is the azimuthal angle."
