awkStatistics generates statistics from csv-data with awk.
AwkStatistics is a script which is used to generate statistical data for csv data
by using awk. It takes two columns from the input file, one is used to identify
the row(option -i) and the other one is the column where the values are
taken from (option -v).
The script was designed for performance engineers to be able to analyze CSV-Data
on the fly and have a good possibility to automate the analysis process.
