Add server code to project. Make client compatible with Edge and IE 11. Modify animation for better performance on Raspberry Pi. Add license and versioning. Add noise suppression to temperature/humidity readings. Add Reload button for reloading the client while it's in kiosk mode. Set up appropriate polyfills. Update README.

+##Astronomy/Weather Clock
+
+To test and build the web client project, you can use the following commands:
+   - "`npm run build`" to build.
+   - "`npm test`" to run unit tests.
+   - "`npm start`" to serve the app using webpack-dev-server.
+   - "`npm run e2e`" to run Protractor.
+
+To run the weather server, use "`npm start`" from within the server directory.
+
+The server requires a Dark Sky API key to function. Use the environment variable `DARK_SKY_API_KEY`
+to set the key. (See https://darksky.net/ for further details.)
+
+To deploy the server along with the web client, use `npm run build` as described above, then copy the
+contents of the `dist` directory into the server's `public` directory.
+
+If you are running the server on a Raspberry Pi, you have the option to provide indoor temperature and
+humidity data using a DHT22/AM2302 sensor, as seen here: https://www.amazon.com/HiLetgo-Temperature-Humidity-Electronic-Practice/dp/B01N9BA0O4/.
+The wiring I will describe is specifically for the AM2302 version of the DHT22, with the built-in pull-up
+resistor.
+
+First, you must install the BCM 2835 library as described here: http://www.airspayce.com/mikem/bcm2835/
+
+Then delete the file in the server directory named `package.json`, followed by renaming the file `package.json.for-dht-sensor.json`
+to `package.json`. Next run `npm install` from within the server directory.
+
+With your Raspberry Pi shut down, and disconnected from power, connect the DHT22/AM2302 sensor.
+The code defaults to assuming the signal lead ("out") of the sensor is connected to GPIO 4 (pin 7 on the GPIO
+header). You can use the environment variable `SENSOR_GPIO` to set a different GPIO number.
+The + lead from the sensor needs to be connect to 5V (I chose pin 2 on the GPIO header) and
+the - lead needs to be connected to ground (I chose pin 6).
+

+
+The web client only displays the indoor temperature and humidity values when connected to the
+web server on `localhost:8080`.
