5// Class for interfacing to the geometry; it also builds and manages two
6// look-up tables for fast access to volumes :
7// 1) the look-up table mapping unique volume ids to symbolic volume names
8// 2) the look-up table mapping unique volume ids to TGeoPNEntries
9// this allows to access directly the functionality of the physical node
10// associated to a given alignable volume by means of its index
