Turku PET Centre web pages are reshaped

Official Turku PET Centre web pages are modernized, and can be found in the familiar place,
http://www.pet.fi and http://www.turkupetcentre.fi.

Responsibility for keeping the pages up-to-date is shared to research groups. If you have suggestions or questions regarding the page contents, please contact the group manager instead of the IT group.

Software downloads and most of the modeling contents are not yet moved to the new pages, but are still found in http://www.turkupetcentre.net.
