* Sn interface to a generic report generating
* class, and to provide the polymorphism necessary to allow the report
* generator to generate any number of different formats of report
*
* Note: This used to be an abstract class, but has been made an interface as there wasn't
* any logic contained within it. It's also been made public, so that you can create a Report
* type without monkeying about in the statistics package.
