    *-*                     ==========================
    *-*
    *-*    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.
