QuakeSim servers updated to port 80

The gw11.quarry.iu.teragrid.org portal server and gf13.ucs.indiana.edu http server have been updated to use port 80 instead of 8080, so that access to the portal is not blocked by any firewalls. This update is completed by running httpd on the same servers and having httpd redirect requests to URL patterns corresponding to QuakeSim portal and resources to the QuakeSim tomcat servers. Therefore, the tomcat servers are still running on port 8080, and services which used to access the web services through 8080 can still work.

The realtime RDAHMM service configurations are modified so that the service now stores all results to directories under tomcat's "webapps" on gf13. The realtime RDAHMM portlet is also modified so that the results are now accessed from gf13 instead of gf14.

XYZ changed to NEU in daily and realtime RDAHMM

The daily and realtime RDAHMM portlets have been updated so that the "Current X", "Current Y", "Current Z" tags are changed to "North", "East" and "Up".
