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.

-/**
- * PhaseShifter effects processor. This unit emulates a common guitar pedal effect but without the
- * LFO modulation. You can use your own modulation source connected to the "offset" port. Different
- * frequencies are phase shifted varying amounts using a series of AllPass filters. By feeding the
- * output back to the input we can get varying phase cancellation. This implementation was based on
- * code posted to the music-dsp archive by Ross Bencina. http://www.musicdsp.org/files/phaser.cpp
