We require the XML export file to include the scores as percentages (and not reals). We do not want the '%' symbol included.

We also require that values be rounded before exporting with 0.5 and above being rounded up.

So 58.2 should be exported as 58
and 60.5 % should be rounded up to 61, etc.

Currently the preview shows scores as reals and the exported file also contains reals.
