// AlignableTransform.h - simple class to hold Identifier and transform for
//                        alignment information
// Richard Hawkings, started 23/9/03
//
// AlignableTransform consists of a vector of AlignTransMember objects,
// each of which is contains an Identifier and a HepGeom::Transform3D
// It is designed to reside in the detector store and be kept in the 
// conditionsDB. The AlignTransTool AlgTool (in DetDescrTools) provides
// a user interface to manage these objects
