Parses a color string into RGB format to be send to a Spark Core via the Spark Cloud API.
Host this server on Heroku or something and make sure to set the PORT environment variable to 80, and the DEVICE_ID and ACCESS_TOKEN environment variables to match those of your Spark Core and account. The server expects a CSS color string (keyword, RGB, HSL, HEX, etc.) in the Body field to POST / (the idea is to set the URL of this server to be hit when an SMS is sent to a phone number given to you by Twilio). The server parses the given CSS color string into RRR,GGG,BBB format and sends it to your Spark Core via the Spark Cloud API at the /color endpoint.
