* Showing reports to the user
* ===========================

* Right now, all subclasses of SS_Report will be shown in the ReportAdmin. However, we are planning
* on adding an explicit registration mechanism, so that you can decide which reports go in the
* report admin, and which go elsewhere (such as the side panel in the CMS).
* Right now, all subclasses of SS_Report will be shown in the ReportAdmin. In SS3 there is only
* one place where reports can go, so this class is greatly simplifed from from its version in SS2.
