This script uses my experimental build tool http://www.bildtool.org

In order to build the complete ANTLR4 product with Java, CSharp, Python 2/3, and JavaScript
targets, do the following from a UNIX command line.  Windows build using this script
is not yet supported.

You will also need python 2.7, python 3.4, node.js and mono (on Mac/Linux)

!!!You might need to set path values in test_properties dictionary below to ensure non Java targets tests run.!!!
