-  Yahoo Weather Forecast parser

- http://developer.yahoo.com/weather/
- This sketch demonstrate how to use the Linux command line tools
- to parse a simple XML file on the Arduino Yún.
- 
- First thing download the XML file from the Yahoo Weather service 
- than use "grep" and "cut" to extract the data you want.
- 
- To find  the location ID of your location, browse or search for your 
- city from the Weather home page. The location ID is in the URL for 
- the forecast page for that city.
