Added examples and updated README.md

[imalberto]

Includes 2 examples:

• a "simple" one showing basic usage
• a "full" one using a more realistic dimensions.json and configuration file

btw if you just use require to load the json data, you can use relative paths, and not need the __dirname, path.join, fs.readFileSync, and JSON.parse.

also running the examples should work regardless of the current working directory (untested) which would make the instructions simpler (i.e. no cd ../../ which is slightly disorienting)
