Detailed Description

Iterator for leaves to be enclosed by bounding volume. Iterator retrieves info about each leaf:

• a set of vertices forming a bounding volume for the leaf
• barycenter (centroid) of leaf

Optionally, the iterator may be able to skip duplicate vertices - i.e., if leaves in the set share vertices.
