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:
