MeasurementCsv: various enhancements

- Added values() and iter_values() methods. These return each row as a
  named tuple, with channel labels as the field names.
- __cmp__ has been made more generic by checking wether other has
  "value" attribute, rather than wether it is an instance of Measurment.
- MeasurementCsv no longer keeps an open handle to the file, and instead
  re-opens the file each time it needs it. This removes the need for
  managing the open handle, and alows parallel iterations over the
  values (each iteration will have it's own read handle into the files).
