title: parse text file and remove commas inside double quotes
body: <p>I have a text file that needs to be converted into a csv file.
  My plan is to:</p>
  
  <ul>
  <li>parse the file line by line</li>
  <li>search and replace commas inside double quotes with a space</li>
  <li>then delete all double quotes</li>
  <li>append the line to a new csv file</li>
  </ul>
  
  <p>Question:
  I need a function that will recognize the comma inside a double quote and replace it.</p>
  
  <p>Here is a sample line:</p>
  
  <p>"MRS Brown","4611 BEAUMONT ST"," ","WARRIOR RUN, PA"</p>
