What Helium does for the Interpreter is just downloading binaries from maven repository. *bin/install-interpreter.sh* is the CLI, which runs InstallInterpreter <https://github.com/apache/zeppelin/blob/master/zeppelin-zengine/src/main/java/org/apache/zeppelin/interpreter/install/InstallInterpreter.java> class.
So, if multiple versions of interpreters are published to a maven repository (with different neo4j driver versions), Helium can help users to download different versions and install. The interpreter maven artifacts are predefined in conf/interpreter-list <https://github.com/apache/zeppelin/blob/master/conf/interpreter-list>, however, *bin/install-interpreter.sh* can download any artifact using '-t' flag.
