Mike's yearly PHP hacking:
* Add a "showclass" param to shownodes so that the node listing will include only nodes of the indicated class. Prepend "no-" to exclude nodes of a particular class. So: showclass=pc,mote would show just pcs and motes. * Now the real reason I added the above: change the hwdown experiment node list to include "showclass=no-pcplabphys" by default so I don't have to flip through 600+ dead plab nodes. Change the URL to "showclass=all" if you want to see plab nodes in hwdown.
