This RFC is for a new tool that reads TMA_Metrics.csv as found on
download.01.org/perfmon and generates metrics and metric groups from
it. To show the functionality the TMA_Metrics.csv is downloaded, but
an accepted change would most likely include a copy of this file from
Intel. With this tool rather than just level 1 topdown metrics, a full
set of topdown metrics to level 4 are generated.

This change was:
Suggested-by: Stephane Eranian <eranian@google.com>
