# . Decide an output directory for coverage output
# . Run ScoverageInstrumenter.scala using the assembled jar file
# . Add scoverage-instrumented class files to jar using 'jar uf target/scala-2.11/$JAR_NAME target/scala-2.11/examples/fuzzable/<name of instrumented jars>'
# . Run a subject program e.g. examples.fuzzable.FlightDistance
# . Process the measurement files produced using CoverageMeasurementConsolidator.scala
