Describe units in documentation

[mwhitworth]

Despite my diving through the eflambe codebase and erlang:trace functionality, it's not really possible to say with confidence what unit the data generated is actually in. (Is it reductions?) It would be clearer to state as part of the initial description what the fundamental unit of measurement is in

Yes, this is really important! They aren't in reductions. Currently the unit output by eflambe should be microseconds, but I want to add support for reductions as well.
