Example Console Usage:
"mallocleak.start report=300" - start tracking leaks and generate a report every 300 secs
"mallocleak report" - report allocations and leaks
"mallocleak stop" - stop tracking leaks
Example Code usage
FMallocLeakReporter::Get().Start(0, 300) - start tracking allocs > 0KB and generate a report every 300 secs
FMallocLeakReporter::Get().WriteReports() - Writes reports and returns the number of suspected leaks
FMallocLeakReporter::Get().WriteReport(TEXT("BigAllocs"), Options); - Write custom report of allocations that matches "Options"
FMallocLeakReporter::Get().Stop() - stop tracking allocations
Reports are written to the profiling dir, e,g GameName/Saved/Profiling/SessionName
