> I'm trying to parse to parse a csv like this:
>  
> {{CSVFormat.DEFAULT}}
> {{ .withHeader()}}
> {{ .withAllowDuplicateHeaderNames(false)}}
> {{ .withAllowMissingColumnNames()}}
> {{ .parse(InputStreamReader(FileInputStream(fl)))}}
>  
> One would expect this code to throw an error if the following csv is given as 
> input:
>  
>  
> {{"","a",""}}
> {{"1","X","3"}}
> {{"3","Y","4"}}
>  
> But it doesn't, and asking for `record.get("")` gives the value from the 
> second column. The first column is ignored.
