// class G4VNestedParameterisation
//
// Class description:
//
// Base class for parameterisations that use information from the parent
// volume to compute the material of a copy/instance of this volume. 
// This is in addition to using the current replication number.
// 
// Notes:
//  - Such a volume can be nested inside a placement volume or a parameterised  
//    volume.
//  - The user can modify the solid type, size or transformation using only
//    the replication number of this parameterised volume.
//    He/she is NOT allowed to change these attributes using information of
//    parent volumes - otherwise incorrect results will occur.
//  Also note that the usual restrictions apply: 
//   - the mother volume, in which these copies are placed, must always be
//     of the same dimensions

// History:
// 24.02.05 - J.Apostolakis - First created version.
