0003 timezone conversion

[sanchezg]

This PR adds timezone conversion addressed by the tz parameter as asked in #3

Also I:

• added a logger method, please use it instead printing to stdout.
• fixed some pep8 issues and minor code style

To test this PR:

import requests

base_url = 'http://localhost:5000/'  # Change it to your settings
api_args = "?sign={sign}&day={day}&tz={timezone}"
req = requests.post(base_url + api_args.format(sign='aries', day='today', timezone='Japan'))

print req.text  # Should print for 'tomorrow'
