class TGeoBoolNode: public TObject

  TGeoBoolNode - base class for Boolean operations between two shapes.

 A Boolean node describes a Boolean operation between 'left' and 'right'
 shapes positioned with respect to an ARBITRARY reference frame. The boolean
 node is referenced by a mother composite shape and its shape components may
 be primitive but also composite shapes. The later situation leads to a binary
 tree hierarchy. When the parent composite shape is used to create a volume,
 the reference frame of the volume is chosen to match the frame in which
 node shape components were defined.

 The positioned shape components may or may not be disjoint. The specific
 implementations for Boolean nodes are:

    TGeoUnion - representing the Boolean  union of two positioned shapes

    TGeoSubtraction - representing the Boolean subtraction of two positioned
                shapes

    TGeoIntersection - representing the Boolean intersection of two positioned
                shapes
