Changes

There Currently, there are currently three subtypes of Raptor-run "scenario" tests, all on (and only on) Android:# '''power-usage tests'''# '''memory-usage tests'''# '''CPU-usage tests'''

==== '''NOTE:'''* it is important that you include '''`--power-test`''', when running power-usage measurement tests, as that will help ensure that local test-measurement data doesn't accidentally get submitted to Perfherder====
