Detailed Description

This structure describes the cached data for one placement held by the volume manager.

This structure is slightly optimized, since there are soooo many instances: If the sensitive volume is associated as a placement to the DetElement, then – placement() returns element.placement() – toElement() returns an identity matrix

If the sensitive volume is NOT the element's placement, then the calls are forwarded to an appended invisible structure at the end of the memory.
