title: Filehelpers field with multiple numbers
body: <p>I wrote a Filehelpers class to read a csv file that contains several fields. In one of these fields, I found that some records have an int, some are blank and some have multiple int separated by a space. When I read the file, an exception is thrown:
  Error. Details: FileHelpers.ConvertException: Error Converting '1960 7423 7439 7578' to type: 'Int32'.</p>
  
  <p>I was wondering how to handle this case. </p>
