8 /// \brief Top container class for geometry transformations
10 /// Geometry transformations can be filled in these ways:
11 /// - by geometry builder when geometry is built via builders
12 /// - from Root geometry file (*.root) or Root geometry manager
13 /// - from ASCII file (*.dat)
14 /// If geometry is loaded from a file, the list of aligned volume paths
15 /// has to be read first from volpaths.dat file.
