// 1:   There are four coordinate systems: BES(the world), local(the mother), temporary local(the temp, for many panels object) 
//  and object, the posterior one is always located in the anterior one.
// 2:   If the local coordinate system of one entity is BES, m_MotOrgInBes is unuseful. 
// 3:   According to the detector structure, the origin coordinates and rotation angles of geometry entities relative to BES 
//  coordinate system can be calculated easily and conveniently, so these values will be initialized first in constructor.
// 4:   For objects having many panels, the id of integral object is -1, and the id of panel begins from 0 to panel number.
//  These objects must be added a temporary local coordinate system for locating the panels, the temporary local
