[logging] debug and trace level messages are added
[csv] switching to CSV Implementation from InMemory implementaion
[BUG] fixing classloader issue

getClass().getClassLoader().getSystemClassLoader().getResourceAsStream(f
ilename) works from eclipse and also from cli:
  java -cp target/classes:CP com.eggs.App
BUT wont work from:
  mvn exec:java -Dexec.mainClass=com.eggs.App

The reason is that maven _doesnt_ fork a new java process, so the extra
getSystemClassLoader() gets the classloader of 'mvn' which doesn't
includes src/main/resources
[exec:java] configuring maven exec plugins so it works as 'mvn exec:java'
