Avoid files - load test data from classpath in src/test/resources
Test using JenaJSONLD.init() RIOT reader instead
Test against RIOT writers - also test with base
Reformat source code (Eclipse default format)
Move JenaJSONLD to src/main/java
No need for TestCase
Added unregister*()
Read with baseURI
Sort + Javadoc
Serialize JSONLD with base
Remove the classic reader/writer (handled through JenaJSONLD.init())
Move all tests to com.github.com.jsonldjava.jena
