From 46888fae6eb7b1dd386f7af7d101ead99ae61981 Mon Sep 17 00:00:00 2001 From: RubbaBoy Date: Mon, 6 Jul 2020 02:33:28 -0400 Subject: 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. --- .classpath | 9 - .gitignore | 14 +- .project | 17 - DEVELOPING.md | 44 ++ README.txt | 1 -
