Running exampl0.
1. Get new libraries from ant.settings.template
2. Compile `ant classesjar`
3. Compile analysis.jar: `ant -f src/soot/rtaclassload/examples/analysis_jar/build.xml jar`
4. Run: `java -cp lib/*:libs/*:../libs/* soot.rtaclassload.examples.example0.Example0 /Users/pcpratts/code/soot_rbcl/src/soot/rtaclassload/examples/analysis_jar/dist/analysis.jar`
