Detailed Description

This class represents an analysis manager for a particular operation instance.

It is used to manage and cache analyses on the operation as well as those for child operations, via nested AnalysisManager instances accessible via 'slice'. This class is intended to be passed around by value, and cannot be constructed directly.
