ff2dbca1 5// AliAlignObj: alignment base class for the storage of the alignment *
6// constants for a single volume: *
7// - a displacement (a shift and a rotation) either as *
8// - the 6 doubles which identify it or as *
9// - the matrix which identifies it *
10// - the identity of the volume itself in form of a symbolic volume *
11// name for alignable volumes, in form of a TGeo path otherwise, *
12// and as a unique integer identifier *
