Detailed Description

Default/Base class to provide a context for registering intersections.

To enable different logic for how individual intersections are accumulated, depending on the usage of ray_intersect_sets().

The API to this context has 3 parts: * getDesiredOrient() during initialization of ray_intersect_sets to determine whether this context filters by context * update_orient() updates the context to know the orientation of the current surface wrt to its volume during a traversal visit() * register_intersection() offers an intersection to the context so that it can decide whether to accumulate it or ignore it

This implementation also provides a default NOP version that accumulates all intersections without logic.

A reference implementation can be found in GeomQueryTool::GQT_IntRegCtxt.
