Class Description

 HGeomVolume

 Class to hold the basic geometry properties of a volume
 Each volume has a name, a pointer to a reference volume and
 a lab transformation.
 The reference volume defines the shape, the mother, the size
 and the transformation relative to the mother volume which
 is either the cave (for modules) or the detector (for the
 inner parts).
 As an example:
 The Mdc modules built at GSI (plane 1 type) are all identical
 independent where the sit in the cave. This module type has a
 fixed coordinate system. The first layers in all these modules
 are identical and they have the same position in the module
 coordinate system.

 copy constructor

 copies all volume parameters except the name

 Creates n Points (objects of class HGeomVector).
 If the array exists already and the size is different from n it is
 deleted and recreated with the new size n.
 If n==0 the points are deleted.

 set the 3 values of the point with index n

 sets point with index n by copying the 3 components of point p

 clears the volume
 deletes the points

 prints all parameters of a volume
