[rules-dev] use of declared facts

[Michal Bali]

Look at this unit test for some examples:
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler/src/test/java/org/drools/integrationtests/MiscTest.java

        // Retrieve the generated fact type
        FactType cheeseFact = ruleBase.getFactType(
"org.drools.generatedbeans.Cheese" );

        // Create a new Fact instance
        Object cheese = cheeseFact.newInstance();

        // Set a field value using the more verbose method chain...
        // should we add short cuts?
        //        cheeseFact.getField( "type" ).getFieldAccessor().setValue(
cheese,
        //
"stilton" );

        cheeseFact.set( cheese,
                        "type",
                        "stilton" );
        assertEquals( "stilton",
                      cheeseFact.get( cheese,
                                      "type" ) );
