JMH reports

[Julien Nicoulaud]

Hi,

Here is some feedback on JMH reports after setting it up on a project:

 * The most convenient format for automating stuff is CSV, but
unfortunately the CSV report only contains raw iterations data, not the
per-test "Mean" and "Mean error" as shown in the text report. Maybe this
could be solved by allowing several output formats at the same time, and
add a "aggregated CSV" output format ?
 * When redirecting output to a file with the --output option, there is no
more output in the console. It would be great to allow to use both at the
same time ?

Regards,
Julien
