unmarshal(CsvDataFormat). different behavior for one or multiples lines.

[dportabella]

unmarshal(CsvDataFormat) produces a List<List<String>>,
however, it the CSV file has only one line, it produces List<String> instead
of List&lt;List&lt;String&gt;>.

We don't know in advance how many lines the CSV file will have,
that could be zero, one, or more than one,
and we should expect to receive always a List&lt;List&lt;String&gt;>.

Is there an option to always receive a List&lt;List&lt;String&gt;> even if
there is only one line?
We didn't find any documentation about this in the website:
http://camel.apache.org/csv.html

David
