The heap profiler records heap allocations, and exports heap dumps via Chrome tracing.
The code is divided into three directories:
- components/services/heap_profiling/ contains the core logic that records allocations.
 - components/heap_profiling/ [this directory] contains
- Logic that hooks up processes to the heap_profiling service [depends on content/].
 - End to end tests [depends on content/].
 
 - chrome/browser/profiling_host/ contains:
- Logic that hooks up UI surfaces to the heap_profiling service.
 - Logic to automatically upload heap dumps in the wild.
