benchmark: use "confidence" in output of compare.R

2017-01-14T06:57:07+00:00

Use the word "confidence" to indicate the confidence level of
the p value so it's easier to understand.
With this change more stars in the output of compare.R means
higher confidence level (lower significance level).

When a benchmark did not contain any parameters the csv configuration
filed would be "". In R this is by default parsed as NA, causing NA in
the printout too.

benchmark: ignore significance when using --runs 1

2016-09-16T18:58:27+00:00

Because the standard deviation can't be calculated when there is only
one observation the R scripts raises an error. However it may still be
useful to run them for non-statistical purposes.

This changes the behaviour such when there is only one observation, the
values that depends on the standard deviation becomes Not Applicable
(NA).

The data sampling is done in node and the data processing is done in R.
Only plyr was added as an R dependency and it is fairly standard.
