A basic command-line weather interface in Python
#!/usr/bin/python
# <Knio> all of the things that remain constant (license, partner, whatever) should me the make class
# <Knio> and then when you ask it something it should return a Results object
# <Knio> and that object has .getTemp() or whatever
# <ScottG> Knio: I thought I had a good reason for setAttr but I don't see it now
# <Knio> so yeah, main class, SearchResults, and WeatherResults
# <Knio> unless searchresults is just like a list of strings, then it doesn't need to be a class
#TODO: Check for version numbers
