Restructured project, added gradle, JUnit, logger, and more

Added Gradle (and removed ant), modernized testing via the JUnit framework, moved standalone examples from the tests directory to a separate module, removed sparsely used Java logger and replaced it with SLF4J. More work could be done, however this is a great start to greatly improving the health of the codebase.
