title: Regex, csv-type layout, allow for "" inside quoted strings?
body: <p>I need a regex that will parse a csv-style file, something like 57 fields wide, most fields enclosed in quotes (but maybe not all), separated by commas, with quoted fields having the possibility of embedded doubles <code>("")</code> that represent single quotes in the evaluated string.</p>
  
  <p>I'm a regex beginner/intermediate, and I think I can get pretty quickly to the basic expression to do the field parsing, but it's the embedded double-quotes (and commas) I can't get my head around.</p>
  
  <p>Anyone?  (Not that it matters but specific language is Matlab.)</p>
