* @brief G4VNestedParameterisation is a 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. 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; it is NOT allowed to change these attributes using information of
* the parent volumes, otherwise incorrect results will occur.
