Class Description

*-*-*-*-*-*-*-*-*-*-*-* T V O L U M E  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.
*-*

*-*-*-*-*-*-*-*-*-*-*Volume normal constructor*-*-*-*-*-*-*-*-*-*-*
*-*                  ================================
*-*
*-*    name    is the name of the node
*-*    title   is title
*-*    shape   is the pointer to the shape definition
