This is destructive. If you want to keep the original data too, you can
implement the same process slightly differently, but this was just cleaner.

to_convert  [:time, :pressure],[0,2.3],[1,4.1],[2,7.56]]

header  o_convert.shift

to_convert.map! do |ary|
  hsh  ash.new
  ary.each_with_index{|val,index| hsh[header[index]]  al }
  hsh
end

to_convert # [{:pressure.3, :time}, {:pressure.1, :time
},
{:pressure.56, :time}]
