/**
 * This must be called during servlet initialization. It sets up the xacml.?.properties file as a system
 * property. If the System property is already set, then it does not do anything. This allows the
 * developer to specify their own xacml.properties file to be used. They can 1) modify the default
 * properties that comes with the project, or 2) change the WebInitParam annotation, or 3) specify an
 * alternative path in the web.xml, or 4) set the Java System property to point to their xacml.properties
 * file. The recommended way of overriding the default xacml.properties file is using a Java System
 * property: -Dxacml.properties=/opt/app/xacml/etc/xacml.admin.properties This way one does not change any
 * actual code or files in the project and can leave the defaults alone.
