# Helper function to run local npm packages with tab completion
# usage: npl pkg options
# Will return 1 if ./node_modules/ or ./node_modules/.bin/pkg doesn't exist
# Otherwise runs ./node_modules/.bin/pkg options
# Run local npm packages
# Better completion thanks to http://stackoverflow.com/a/14524311
