/**
 * This class acts as an interface to the xml service of weather.com. It
 * searches for given locations and retrieves current weather data as well
 * as forecast for up to 5 days.
 *
 * For using the weather.com xml-service please visit
 *     http://www.weather.com/services/xmloap.html
 * and follow the link to sign up, it's free! You will receive an email
 * where to download the SDK with the needed images and guidelines how to
 * publish live data from weather.com. Unfortunately the guidelines are a
 * bit harsh, that's why there's no actual data-representation in this
 * class, just the raw data. Also weather.com demands active caching, so I'd
 * strongly recommend enabling the caching implemented in this class. It
 * obeys to the times as written down in the guidelines.
 *
 * For working examples, please take a look at
 *     docs/Services_Weather/examples/weather.com-basic.php
 *     docs/Services_Weather/examples/weather.com-extensive.php
