Create test setup

A complete pipeline has to be created:

• phase ros2rag: input = relast grammar and ros2rag specification. output = relast grammar (modified), generated ros2rag-aspect and mqtt-updater
• phase relast: input = relast grammar (modified). output = jastadd grammar, generated relation aspect(s)
• phase jastadd: input = jastadd grammar, generated ros2rag-aspect, generated relation aspect(s). output = java files
• phase compileJava: input = java files. output = errors class files
• phase test: uses the compiled files and run the test
