title: Apache commons csv
body: <p>I can't understand the core of apache commons csv library. 
  Could you advice a method I should use when I want to get columns by header name from csv file by apache-commons-csv?
  For example, I have such csv file:</p>
  
  <pre><code>Delays, Computation time, Communication time
  0., 500000, 10
  20., 563210, 20
  55., 546541., 23.
  12., 465487., 23.
  45., 456547., 28.
  87., 985458., 56.
  47., 456778., 45.
  </code></pre>
  
  <p>I want to get arrays: double[] delays, double[] compTime, double[] commTime consist of values from csv.</p>
