    added script to node-local testing for running test.js via the action… (#38)

+## using npm libraries
+
+If your action uses npm libraries, you may have trouble running it locally without creating a special environment just for it to run.
+
+In this case you can run the docker image that open whisk uses to launch your action, along with its preinstalled libraries:
+
+```bash
+./runtest.sh --debug --action ./path-to-function.js --param name=value --param othername=othervalue
+```
+
+Usage:
+* --debug : enable request debugging (by adding NODE_DEBUG=request)
+* --action : action js file you are trying to test 
+* --param : parameter to pass to main (multiple allowed)
+* --image : the action image used to run node (default is openwhisk/nodejs6action:latest)
