/**
 * Conformance is an application that runs a <code>ConformanceTestSet</code> and dumps results comparing the actual and
 * expected results.
 * 
 * TO RUN in Eclipse:
 * This is run as a Java Application.
 * You must first create a Run/Debug Configuration: 
 * 		Under the Argument tab, in Program Arguments you must set the -i or --input command line argument.
 *	 	You should also direct the output to a file using -o or --output. (default is Console)
 *		See the init() method in this file for other useful arguments.
 * 		Example for a Windows machine:
 * 			-i testsets/conformance/xacml3.0-ct-v.0.4
 * 			-o \Users\yourLogin\Downloads\conformance.txt
 * 		You must also set the VM arguments:
 * 			-Dxacml.properties=testsets/conformance/xacml.properties .
 * 			-Dlog4j.configuration=.\logging.properties
 * 
 * @version $Revision: 1.2 $
