title: double quoted elements in csv cant read with pandas
body: <p>I have an input file where every value is stored as a string.
  It is inside a csv file with each entry inside double quotes.</p>
  
  <p>Example file:</p>
  
  <pre><code>"column1","column2", "column3", "column4", "column5", "column6"
  "AM", "07", "1", "SD", "SD", "CR"
  "AM", "08", "1,2,3", "PR,SD,SD", "PR,SD,SD", "PR,SD,SD"
  "AM", "01", "2", "SD", "SD", "SD"
  </code></pre>
  
  <p>There are only six columns. What options do I need to enter to pandas read_csv to read this correctly?</p>
  
  <p>I currently am trying:</p>
  
  <pre><code>import pandas as pd
  df = pd.read_csv(file, quotechar='"')
  </code></pre>
  
  <p>but this gives me the error message:
  <code>CParserError: Error tokenizing data. C error: Expected 6 fields in line 3, saw 14</code></p>
  
  <p>Which obviously means that it is ignoring the '"' and parsing every comma as a field.
  However, for line 3, columns 3 through 6 should be strings with commas in them. ("1,2,3", "PR,SD,SD", "PR,SD,SD", "PR,SD,SD")</p>
  
  <p>How do I get pandas.read_csv to parse this correctly?</p>
  
  <p>Thanks.</p>
