Ignore the MYMETA.json file
Fix off by one error.

To calculate the cumulative values, we would iterate
beyond the timer values array limit, causing a warning
for addition of an undefined value.

Results would be still correct, but the warning sucked.
Test cases (to be committed soon) revealed that.
Be 100% compatible with etsy's statsd.

Perl's int(x) != Javascript Math.round(x)
Compensate for that, and make the two statsd
implementations behave 100% in the same way
when it comes to selecting thresholds for percentiles.
Metrics processing tests, from etsy's statsd.

Converting these tests actually found two subtle
bugs in the metrics processing code, in the cumulative
values calculations and in the timer percentile threshold
selection. Nice :)
Avoid a bunch of debugging/profiling files
