Class Description

 Manages a detector rotation matrix. See class TGeometry.

*-*-*-*-*-*RotMatrix normal constructor defined a la GEANT*-*-*-*-*-*-*
*-*        ===============================================

 The TRotMatrix constructor with six angles uses the GEANT convention:

 theta1 is the polar angle of the x-prim axis in the main reference system
 (MRS), theta2 and theta3 have the same meaning for the y-prim and z-prim
 axis.

 Phi1 is the azimuthal angle of the x-prim in the MRS and phi2 and phi3
 have the same meaning for y-prim and z-prim.


 for example, the unit matrix is defined in the following way.

     x-prim || x, y-prim || y, z-prim || z

     means:  theta1=90, theta2=90, theta3=0, phi1=0, phi2=90, phi3=0
