-Added: Tests for all map implementations. -Added: Missing Map Constructors. -Fixed: Bugs with Maps & Sets. -Fixed: Gradle Java Container. -Fixed: Some javadoc stuff. -Note: SubMap/List implementation are not really well tested and most likely buggy -Changed: set JavaDoc to be quiet for now. Later goal.
