Class Description

*-*                     ==========================
*-*
*-*    A TVolume object is used to build the geometry hierarchy.
*-*    Since TVolume is derived from TDataSet class it may contain other volumes.
*-*
*-*    A geometry volume has attributes:
*-*      - name and title
*-*      - pointer to the referenced shape (see TShape).
*-*      - list of TVolumePosition object defining the position of the nested volumes
*-*        with respect to the mother node.
*-*
*-*
*-*    A volume can be drawn.

*-*
*-*    name    is the name of the node
*-*    title   is title
*-*    shapename is the name of the referenced shape

 Paint shape of the volume
 To be called from the TObject::Paint method only

 DeletePosition deletes the position of the TVolume *node from this TVolume
 and removes that volume from the list of the nodes of this TVolume

  GetRange

  Calculates the size of 3 box the volume occupies,
  Return:
    two floating point arrays with the bound of box
