NodeJS Wrapper - run binary locally

Node.js wrapper which will download and proxy to node locally. This allows you to automatically manage the installed version of node.

CONFIGURATION

NODEW_INSTALL_VERSION - an env variable to specify the version of node to install - Defaults to 4.4.7 NODEW_DIST_BASE_URL - an env variable to specify the binary download location - Defaults to NodeJS website

Sample usage: ./npmw install express --save
