:pq_parse v0.1: parse and write to csv
      puts "got: " + line
Committing error-free complex version: pq_parse.rb

pq_parse.rb works, (parsing, cleansing) but does not yet do correct
aggregations of figures nor options parsing nor plotting.

Restart working on simple, straightforward version (pq_iostat.rb)

Backed-up old straightforward version of pq_iostat.rb to pq_iostat_01.rb
pq_iostat.rb - initial version, only minor deviations from Werners scripts
