Detailed Description

A wrapper arround UsdGeomBBoxCache.

This singleton class keeps a cache per stage and per purpose. It will be flushed when the stage cache is flushed.

Unfortunaly UsdGeomBBoxCaches only store a single frame at a time. I considered creating a cache per frame but I thought that would defeat optimizations for non animated geometry.
