/*****************************************************************************
 * AliAlignObjAngles: derived alignment class storing alignment information  *
 *   for a single volume in form of three doubles for the translation        *
 *   and three doubles for the rotation expressed with the euler angles      *
 *   in the xyz-convention (http://mathworld.wolfram.com/EulerAngles.html),  *
 *   also known as roll, pitch, yaw. PLEASE NOTE THE ANGLES SIGNS ARE        *
 *   INVERSE WITH RESPECT TO THIS REFERENCE!!! In this way the representation*
 *   is fully consistent with the TGeo Rotation methods.                     *
