def raw_yahoo_weather(location_id, metric=True):
"""
Fetches weather report from Yahoo!
Note that this returns a lot more than weather.
Parameters
location_id: The WOEID of the location, get_woeid() can retreive it.
metric: type of units. True for metric and False for US units
Note that choosing metric units changes all the weather units to metric, for example, wind speed will be reported as kilometers per hour and barometric pressure as millibars.
Returns:
weather_data: a dictionary of weather data that exists in XML feed. See http://developer.yahoo.com/weather/#channel
