HierarchyFrameDataView

Description

Provides access to the Profiler data for a specific frame and thread.

Use HierarchyFrameDataView to retrieve Profiler samples structured as a hierarchy.
This is used in the Hierachy mode of the CPU Usage Profiler, for example.

The HierarchyFrameDataView aggregates the data with time and memory information. Each hierarchy item includes accumulated data of its children.
