List Servers and Domains

/* Example Program : 

	 Obtain lists of servers and domains for each AADS specified on the command line.

     Compile: javac -classpath sconfig.jar;jaas.jar;wcp.jar ListServersAndDomains.java

     Run: java -classpath sconfig.jar;jaas.jar;wcp.jar ListServersAndDomains <AADS1> ;[AADS2] ... [AADSn]

	 Before running this program, run the 'ObtainAADSCertificates' program to obtain certificates
       for the AADS servers of interest.
