Switched to use `child_process.spawn`. This fixes node using lots of cpu time when a unit test is running and logging a lot.
Also fixes bug with large amounts of console writes causing the node instance to crash.
Updated readme.md and package.json
Removed wrapping quotes, child_process::spawn handles those for us.
Minor cleanup.
Updated tests.
cleanup commented out code as well as return indentation to using tabs instead of spaces
Merge branch 'feature/spawn-insteadof-exec' into develop
