Making use of the closure-util package

This provides some initial development utilities for people using Node.

Instructions for installing:

    npm install

After pulling down the dependencies, you can start a developement server that provides the libraries (ol and Closure Library) in debug mode (not minified/compiled).  Run the dev server with the following:

    npm start

Currently, the example index page needs to be built with `build.py`.  After building that, you should be able to browse all static files, view the examples and run the tests.
