closes #450. READ COMMENTS IN PR450 FOR INSTRUCTIONS ON USAGE We'll put these instructions some place better soon. Also replace globule with globby ( perf issues) and explicitly exclude node_modules where possible. Updated _examples/package.json for latest 3rd party libs (e.g. alpha.48) and updated template-syntax/ts/package.json to be a prototypical example
